raw_input accepts value and return it as a string. So when you enter 1 or 2, it is returned as '1' or '2'.

You have to typecast the input value into int explicitly:

value=int(raw_input("Enter value to print month "))

Or,you can use input() to accept user input as:

value = input("Enter value to print month ")

Using `input` on Python 2 is like opening the gates of hell for your code. – Matthias Apr 18 '18 at 08:02

Your problem is that your "switcher" dictionary has integer keys, and argument is a string when you call

print switcher.get(argument, "Invalid month")

One possible solution is to cast argument to int, it should then work.

print switcher.get(int(argument), "Invalid month")

calling function by user input?
