[SOLVED] How can I accept default parameter in function when 'None' or no argument is passed?


I am writing a new python class with a generic function. At one point I have a requirement as follows

def function(a=1):
    print a # here I want a to be 1 if None or nothing is passed


  • a(None) should print 1
  • a() should print 1
  • a(2) should print 2

Is there a way to do this?


You can define a function with a default argument, later you can check for the value passed and print it:

def fun(a=1):
    a = 1 if a is None else a
