-* Outline
- - ~for~ loop in Python.
- - Blocks of code in Python.
- - Indentation
-* Whitespace in Python
- - Whitespace is significant
- - blocks are visually separated
- - Blocks are indented using 4 spaces
- : Block A
- : Block A
- : Block B
- : Block B
- : Block A
- ~Block B~ is an inner block and is indented using 4 spaces
-* Exercise 1
- Write a ~for~ loop which iterates through a list of numbers and find
- the square root of each number.
- :
- The numbers are,
- : 1369, 7225, 3364, 7056, 5625, 729, 7056,
- : 576, 2916
-* Solution 1
- - Open text editor and type the following code
- #+begin_src python
- numbers = [1369, 7225, 3364, 7056, 5625, 729, 7056,
- 576, 2916]
-
- for each in numbers:
- print "Square root of", each, "is", sqrt(each)
-
- print "This is not in for loop!"
- #+end_src
-* Save \& run script
- - Save the script as ~list_roots.py~
- - Run in ~ipython~ interpreter as,
- : In []: %run -i list_roots.py
-* Exercise 2
- From the given numbers make a list of perfect squares and a list of those which are not.
- :
- The numbers are,
- : 7225, 3268, 3364, 2966, 7056, 5625, 729, 5547,
- : 7056, 576, 2916
-* Exercise 3 (indentation in ~ipython~)
- Print the square root of numbers in the list.
- :
- Numbers are,
- : 7225, 3268, 3364, 2966, 7056, 5625, 729, 5547,
- : 7056, 576, 2916
-* Indentation in ~ipython~
- : In []: numbers = [1369, 7225, 3364, 7056, 5625,
- : ...: 729, 7056, 576, 2916]
-
- : In []: for each in numbers:
- : ...:
- Note the four spaces here
- :
- :
- :
- :
- :
- :
-* Indentation in ~ipython~ (cont'd)
- : In []: numbers = [1369, 7225, 3364, 7056, 5625,
- : ...: 729, 7056, 576, 2916]
- : In []: for each in numbers:
- : ...:
- Note the four spaces here
- :
- Now type the rest of the code
- : ...: print "Square root of", each,
- : ...: print "is", sqrt(each)
- : ...:
- : ...:
-* Indentation in ~python~ interpreter
- Find out the cube of all the numbers from 1 to 10.
- :
- /do it in the python interpreter/
-* Indentation in ~python~ interpreter (cont'd)
- #+begin_src python
- >>> for i in range(1, 11):
- ... print i, "cube is", i**3
- ...
- #+end_src
-* ~range()~ function
- - in built function in Python
- - generates a list of integers
- - /syntax:/ range([start,] stop[, step])
- - /example:/
- - range(1, 20) - /generates integers from 1 to 20/
- - range(20) - /generates integers from 0 to 20/
-* Exercise 4
- Print all the odd numbers from 1 to 50.
-* Summary
- - blocks in ~python~
- - indentation
- - blocks in ~ipython~ interpreter
- - ~for~ loop
- - iterating over list using ~for~ loop
- - ~range()~ function
-* Thank you!
