Control Structures in Python

This Program explains different control structures in python

If
====
# basic "If"
if boolean:
    x = 1
else:
    x = 0

# Not so basic "If"
# Notice the new keywords!
if (boolean and otherboolean) or ( not boolean ):  #oops, this is just if(boolean), oh well...  :~)
    x = 1
elif not otherboolean:
    x = 0
else:
    x = 100000000000000000000 # Big numbers make if statements less boring!

While
=====

# This is it...  
while i < 100:
    i + 1

# More generally:
while condition == true:
    """do the following"""
    ...
    ...
    condition = false.

# Infinite Loop:
while 1:
    print "I'm loopy!"


FOR
====

# Basic For Loop
for item in list:
    dosomething(item)

# The traditional C for loop has a different form in Python:
for x in range(0, 100):
    dosomething(x)

# More interesting example:
def buglove( UIUC ):
    for bug in UIUC:
        if type( bug ) == type( chinese_lady_beetle() ):
            crush( bug )
        else:
            hug( bug )
