* 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
* Summary
- Number Datatypes -- integer,float and complex
- Boolean and datatype and operators
- Sequence data types -- List, String and Tuple
- Accesing sequence
- Slicing sequences
- Finding length, sorting and reversing operations on sequences
- Immutability
* Thank you!
