Identation

This is the very important part specially in python language.

• Increase indent after an if or for statement [after :]
• Maintain indent to indicate the scope of the block.
• Reduce indent back to the level of the if or for statement to indicate that the end of the block.
• Blank lines are ignored
• Comment on a line by themselves are ignored with regard to the identation.

Example:

x = 5
if x > 2:
    print('Bigger than 2')
    print('Still Bigger')
print('Done with 2')

for i in range(5):
    print(i)
    if i > 2:
        print('Bigger than 2')
    print('Done with i', i)
print('All Done')
