#
# This is a variable used in the examples below.
#

something = 4

#
# This code creates a local variable x and then uses it.
#

x = 2
# ... do some stuff
return x * something

#
# This code accomplishes the same result without a local variable
# by calling a function with a parameter x.
#


def helper(x):
    # ... do some stuff
    return x * something


return helper(2)

#
# This code accomplishes the same result without a local variable
# and without a named function using a Python lambda.
#

(lambda x: x*something)(2)
