Python function problem

[kieranlavelle]

Can someone please explain to me why this is not working.

def x():
u = input("Please enter your name: ")
x()
Please enter your name: Kieran
print(u)

Name Error: Name 'u' is not defined.

How do i go about defining a variable whilst creating a function?
ps I am new to python and coding in general as im sure you can tell.

Ahh I see now, the variable is local. Is there anyway I can use these variables outside of the function itself?
