-* 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!
