1. The problem statement, all variables and given/known data I am trying to write a program in which I have a function that uses the variable x. For example, def function(x): x=x+2 return x function(4) Now I want to print out what x was inside the function. I thought I would just say "print function(4)", but it's giving me an error message. "print function(x)" doesn't work either. What am I doing wrong?
