@masoud mansouri: can you please post the complete error message. This means all of the red text. It contains lots of useful information for us.

If you want to use the input function to input a string (that your inline call will use), you need to add 's' to the prompt:
a=input('enter fun', 's')

I wrote the correct input call in my original Answer. Insert my ‘a’ assignment in place of yours and it should work correctly:
a=input('enter fun', 's')
