-Hello friends and welcome to the tutorial on Basic Data types and operators
-in Python.
-
-{{{ Show the slide containing title }}}
-
-{{{ Show the slide containing the outline slide }}}
-
-In this tutorial, we shall look at
-
-* Datatypes in Python
-    * Numbers
-    * Boolean
-    * Sequence
-* Operators in Python
-  * Arithmetic Operators
-  * Boolean Operators
-
-* Python Sequence Data types
-  * list
-  * string
-  * tuple
-
-First we will explore python data structures in the domain of numbers.
-There are three built-in data types in python to represent numbers.
-
-{{{ A slide to make a memory note of the different datatypes }}}
-
-These are:
-
-  * int 
-  * float 
-  * complex 
-
-Lets first talk about int. ::
-
-   a = 13
-   a
-
-
-Now, we have our first int variable a.
-
-
-If we now see ::
-     
-   type(a)
-   <type 'int'>
-
-This means that a is a type of int. There are lot of functions associated
-with the int datatype, to manipulate it in different ways. These can be
-explored by doing, ::
-
-  a.<Tab>
-
-*int* datatype can hold integers of any size lets see this by an example.
-::
-
-  b = 99999999999999999999
-  b
-
-As you can see even when we put a value of 9 repeated 20 times python did
-not complain. This is because python's int data-type can hold integers of any
-size.
-
-Let us now look at the float data-type. 
-
-Decimal numbers in python are represented by the float data-type ::
-
-  p = 3.141592
-  p
-
-If you notice the value of output of ``p`` isn't exactly equal to ``p``.
-This is because computer saves floating point values in a specific format.
-There is always an approximation. This is why we should never rely on
-equality of floating point numbers in a program.
-
-The last data type in the list is complex number ::
-
-  c = 3.2+4.6j
-
-as simple as that so essentialy its just a combination of two floats the
-imaginary part being defined by j notation instead of i. Complex numbers
-have a lot of functions specific to them. Let us look at these ::
-
-  c.<Tab>
-
-Lets try some of them ::
-
-  c.real
-  c.imag
-
-c.real gives the real part of the number and c.imag the imaginary.
-
-We can get the absolute value using the function ::
- 
-  abs(c)
-
-
-Following is are exercises that you must do. 
-
-%% %% Find the absolute value of 3+4j 
-::
-
-        abs(3+4j)
-
-%% %% What is the datatype of number 999999999999999999? Is it
-not int?
-::
-
-        Long
-        Big integers are internally stored in python
-        as Long datatype.  
-
-Please, pause the video here. Do the exercises and then continue. 
-
-
-{{ Slide for showing Boolean datatypes }} 
-
-Python also has Boolean as a built-in type.
-
-Try it out just type ::  
-
-  t = True
-
-note that T in true is capitalized.
-  
-You can apply different Boolean operations on t now for example ::
-
-  f = not t 
-  f
-  f or t
-  f and t 
-
-
-The results are self explanatory.
-
-What if you want to apply one operator before another.
-
-Well you can use parenthesis for precedence.
-
-Lets write some piece of code to check this out.::
-
-  a=False 
-  b=True 
-  c=True
-
-
-To check how precedence changes with parenthesis, we will try two
-expressions and their evaluation.
-
-one ::
- 
-  (a and b) or c
- 
-This expression gives the value True
-
-where as the expression :: 
-  
-  a and (b or c) 
-
-gives the value False.
-
-
-Let's now look at some operators available in Python to manipulate
-these data types.
-
-Python uses '+' for addition ::
-
-  23 + 74
-
-'-' for subtraction ::
-
-  23 - 56
-
-'*' for multiplication ::
- 
-  45*76
-
-'/' for division ::
-    
-  384/16
-  8/3 
-  8.0/3
-
-When we did 8/3 the first case results in am integer 
-output as both the operands are integer however when 
-8.0/3 is used the answer is float as one of the operands is
-float. 
-
-
-'%' for modulo operation ::
-
-    87 % 6
-
-and two stars for a exponent. ::
-
-    7**8
-
-
-In case one wishes to use the current value of variable in which the result
-is stored in the expression one can do that by putting the operator before
-`equal to`. ::
-
-   a=73
-   a*=34
-
-is same as ::
-   
-   a=a*34
-
-and ::
-
-    a/=23
-
-is same as ::
-
-   a=a/23
-
-Following is are exercises that you must do. 
-
-%% %% Using python find sqaure root of 3?
-
-%% %% Is 3**1/2 and 3**0.5 same
-
-Please, pause the video here. Do the exercises and then continue.
-
-::
-
-   3**0.5
-
-::
-    No,One gives an int answer and the other float        
-
-
-Lets now discuss sequence data types in Python. Sequence data types
-are those in which elements are kept in a sequential order and all the 
-elements are accessed using index numbers.
-
-{{{ slide introducing sequence datatype }}}
-
-The sequence datatypes in Python are ::
-
- * list
- * string
- * tuple
-
-The list type is a container that holds a number of other objects, in the
-given order.
-
-We create our first list by typing :: 
-  
-  num_list = [1, 2, 3, 4]
-  num_list
-
-
-Items enclosed in square brackets separated by comma constitutes a list.
-
-Lists can store data of any type in them.
-
-We can have a list something like ::
-
- var_list = [1, 1.2, [1,2]]	
- var_list
-
-Lets look at another sequence data type, strings
-
-type :: 
-
-  greeting_string="hello"
-
-
-greeting_string is now a string variable with the value "hello"
-
-{{{ All the different types of strings shown }}}
-
-Python strings can actually be defined in three different ways ::
-
-   k='Single quote'
-   l="Let's see how to include a single quote"
-   m='''"Let's see how to include both"'''
-
-As you can see, single quotes are used as delimiters usually.
-
-When a string contains a single quote, double quotes are used as
-delimiters. When a string quote contains both single and double quotes,
-triple quotes are used as delimiters.
-
-The last in the list of sequence data types is tuple.
-
-To create a tuple we use normal brackets '(' unlike '[' for lists.::
-
-   num_tuple = (1, 2, 3, 4, 5, 6, 7, 8)
-  
-Because of their sequential property there are certain functions and
-operations we can apply to all of them.
-
-
-
-The first one is accessing.
-
-They can be accessed using index numbers ::
-
-   num_list[2]
-   num_list[-1]
-   greeting_string[1]
-   greeting_string[3]
-   greeting_string[-2]
-   num_tuple[2]
-   num_tuple[-3]
-
-
-Indexing starts from 0 from left to right and from -1 when accessing lists
-in reverse. Thus num_list[2] refers to the third element 3. and greetings
-[-2] is the second element from the end , that is 'l'.
-
-
-
-Addition gives a new sequence containing both sequences ::
-
-      num_list+var_list
-      a_string="another string"
-      greeting_string+a_string
-      t2=(3,4,6,7)
-      num_tuple+t2
-
-len function gives the length ::
-
-   len(num_list)
-   len(greeting_string)
-   len(num_tuple)
-
-Prints the length the variable.
-
-We can check the containership of an element using the 'in' keyword ::
-
-   3 in num_list
-   'H' in greeting_string
-   2 in num_tuple
-
-We see that it gives True and False accordingly.
-
-Find maximum using max function and minimum using min::
-
-   max(num_tuple)
-   min(greeting_string)
-
-Get a sorted list  ::
-
-   sorted(num_list)
-   
-
-As a consequence of their order, we can access a group of elements in a
-sequence, together. This is called slicing and striding.
-
-First lets discuss Slicing, 
-
-Given a list ::
-
-  j=[1,2,3,4,5,6]
-
-Lets say we want elements starting from 2 and ending in 5.
-
-For this we can do ::
-
-   j[1:4]
-
-The syntax for slicing is, sequence variable name square bracket first
-element index, colon, second element index. The last element however is not
-included in the resultant list::
-
-
-   j[:4]
-
-If first element is left blank default is from beginning and if last
-element is left blank it means till the end.
-
-::
-
-  j[1:]
-
-  j[:]
-
-This effectively is the whole list.
-
-Striding is similar to slicing except that the step size here is not one.
-
-Lets see by example ::
-
-  new_num_list=[1,2,3,4,5,6,7,8,9,10]
-  new_num_list[1:8:2]
-  [2, 4, 6, 8]
-
-The colon two added in the end signifies all the alternate elements. This
-is why we call this concept striding because we move through the list with
-a particular stride or step. The step in this example being 2.
-
-We have talked about many similar features of lists, strings and tuples.
-But there are many important features in lists that differ from strings and
-tuples. Lets see this by example.::
-
-   new_num_list[1]=9
-   greeting_string[1]='k'
-
-{{{ slide to show the error }}}
-
-
-
-As you can see while the first command executes with out a problem there is
-an error on the second one.
-  
-Now lets try ::
-
-   new_tuple[1]=5
-
-Its the same error. This is because strings and tuples share the property
-of being immutable. We cannot change the value at a particular index just
-by assigning a new value at that position.
-
-
-We have looked at different types but we need to convert one data type into
-another. Well lets one by one go through methods by which we can convert
-one data type to other:
-
-We can convert all the number data types to one another ::
-
-  i=34
-  d=float(i)
-  d  
-
-Python has built in functions int, float and complex to convert one number
-type data structure to another.
-
-::
-
-  dec=2.34
-  dec_con=int(dec)
-  dec_con
-
-
-As you can see the decimal part of the number is simply stripped to get the
-integer.::
-
-  com=2.3+4.2j
-  float(com)
-  com
-
-In case of complex number to floating point only the real value of complex
-number is taken.
-
-Similarly we can convert list to tuple and tuple to list ::
-  
-  lst=[3,4,5,6]
-  tup=tuple(lst)
-  tupl=(3,23,4,56)
-  lst=list(tuple)
-
-However converting a string to a list and a list to a string is an
-interesting problem. Let's say we have a string ::
-
-  In: somestring="Is there a way to split on these spaces."
-  In: somestring.split()
-
-
-This produces a list with the string split at whitespace. Similarly we can
-split on some other character.
-
-::
-
-  In: otherstring="Tim,Amy,Stewy,Boss"
-
-How do we split on comma , simply pass it as argument ::
-
-  In: otherstring.split(',')
-
-join function does the opposite. Joins a list to make a string.::
-
-  ','.join['List','joined','on','commas']
-
-Thus we get a list joined on commas. Similarly we can do spaces.::
-
-  ' '.join['Now','on','spaces']
-
-Note that the list has to be a list of strings to apply join operation.
-
-With this we come to the end of this tutorial .
-
-Following is an (are) exercise(s) that you must do. 
-
-
-
-%% %% Check if 3 is an element of the list [1,7,5,3,4]. In case
-it is change it to 21.
-::
-        l=[1,7,5,3,4]
-        3 in l
-        l[3]=21
-        l
-
-%% %% Convert the string "Elizabeth is queen of england" to 
-"Elizabeth is queen"
-::
-
-           s="Elizabeth is queen of england"
-           stemp=s.split()
-           ' '.join(stemp[:3])
-   
-Please, pause the video here. Do the exercise(s) and then continue. 
-
-
-This brings us to the end of the tutorial. In this tutorial we have
-discussed
-
-1. Number Datatypes , integer,float and complex 
-2. Boolean and datatype and operators
-3. Sequence data types ,List,String and Tuple

-* Outline 
-** Datatypes in Python
-*** Numbers
-*** Boolean
-*** Sequence
-** Operators in Python
-*** Arithmetic Operators
-*** Boolean Operators
-** Python Sequence Datatypes
-*** list
-*** string
-*** tuple
-
-* Numbers
-  - int
-  - float
-  - complex
-* Question 1
-   - Find the absolute value of 3+4j 
-* Solution 1
-  #+begin_src python
-    abs(3+4j)
-  #+end_src python
-* Question 2
-  - What is the datatype of number 999999999999999999? Is it
-not int?
-
-* Solution 2
-  - Long
-  - Large integers numbers are internally stored in python as Long
-    datatype.
-
-
-* Boolean
-  #+begin_src python
-    In []: t=True
-    In []: f=False
-  #+end_src
-
-* Question 3
-  - Using python find sqaure root of 3?
-
-* Solution 3
-
-  - 3**0.5
-
-* Question 4
-  - Is 3**1/2 and 3**0.5 same
-* Solution 4
-  - No,One gives an int answer and the other float        
-
-* Sequence Data types
-** Properties
- - Data in Sequence 
- - Accessed using Index
-** Type
- - list
- - String
- - Tuple
-
-* All are Strings
-   #+begin_src python 
-      k = 'Single quote'
-      l = "Double quote contain's single quote"
-      m = '''"Contain's both"'''
-
-    #+end_src 
-* Immutabilty Error
-   #+begin_src python
-      In []: greeting_string[1]='k'
-      -------------------------------------------------------
-      TypeError           Traceback (most recent call last)
-
-      /home/fossee/<ipython console> in <module>()
-
-      TypeError: 'str' object does not support item assignment
-   #+end_src 
-
-* Question 5
-  Check if 3 is an element of the list [1,7,5,3,4]. In case it is
-change it to 21.
-
-* Solution 5
-     #+begin_src python
-        l=[1,7,5,3,4]
-        3 in l
-        l[3]=21
-        l
-     #+end_src
-* Question 6
-  Convert the string ~"Elizabeth is queen of england"~ to ~"Elizabeth is
-queen"~
-
-* Solution 6
-     #+begin_src python
-    s = "Elizabeth is queen of england"                                                                                                                 
-    stemp = s.split()                                                                                                                                   
-    ' '.join(stemp[:3])                                                                                                                               
-    #+end_src
