Lists assignments
There is an easy and elegant way to assign values in a list using an operation:



list=[]
for x in range(5):
    list.append(x*x)

is the same as:

list = [x*x for x in range(5)]

IF statements (python 2.5)

if a > b:
    x = a
else:
    x = b

is the same as:

x = a if a > b else x = b

Method __call__
You can use the __call__ function to define a function without specifying a function name.

def __call__(self, name):
    print "Hello %s"%name

You can then call this method without mentioning a method identifier

a=A()
a('John')
