while statements frame loops. In English, do the indented commands WHILE this condition is true. In code:

while( 2 > 1 ):
print "Boring, isn't it?"

The condition, in this style, is inside the parenthesis. This loop will run forever.

An if statement kind of just frames a condition and branches based on whether the condition is true or not.

if( 2 > 1 ):
print "No kidding."
elif( 2 == 1 ):
print "Not likely"
else: # any other outcome
print "Didn't happen"

Other languages require the parenthesis, Python allows them.
