Python: Lamda functions

# anonymous functions:

>>> add = lambda x, y: x + y
>>> add(5, 3)
8

# You could declare the same add() 
# function with the def keyword:

>>> def add(x, y):
...     return x + y
>>> add(5, 3)
8

# So what's the big fuss about?
# Lambdas are *function expressions*:
>>> (lambda x, y: x + y)(5, 3)
8

# • Lambda functions are single-expression 
# functions that are not necessarily bound
# to a name (they can be anonymous).

# • Lambda functions can't use regular 
# Python statements and always include an
# implicit `return` statement.
