In Python, functions are defined as follows:<\/p>\n

<\/pre>\n
\ndef addTwoNumbers(a, b):
\n  return a + b<\/p>\n
x = 3
\ny = 4
\nresult = addTwoNumbers(x, y)
\nprint(‘The sum of {} and {} is {}’.format(x, y, result))<\/p>\n
\nPython also supports setting default values for the input parameters. Example:<\/p>\n
<\/pre>\n
\ndef addTwoNumbers(a = 3, b = 2):
\n  return a + b<\/p>\n
result = addTwoNumbers()
\nprint(‘The result of addTwoNumbers() is: {}’.format(result))
\nresult = addTwoNumbers(4)
\nprint(‘The result  of addTwoNumbers(4) is: {}’.format(result))<\/p>\n
\nShorthand lambda functions are defined as follows:<\/p>\n
<\/pre>\n
\nresult = lambda a, b : a + b
\nprint(‘The result of lambda a, b is: {}’.format(result(3, 4)))<\/p>\n
\nFunctions with variable length parameters are defined as follows:<\/p>\n
<\/pre>\n
\ndef addNumbers(*argv):
\n  result = 0
\n  for arg in argv: 
\n    result += arg
\n  return result<\/p>\n
result = addNumbers(1, 2, 3)
\nprint(‘The result of addNumbers(1, 2, 3) is: {}’.format(result))<\/p>\n
