+* 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!
