Python Spyder function error

[rube3459]

Hello,
I am writing this very simple function in Spyder:



Python: Copy to Clipboard


Def square(X):
Print(x**2)

Then I select this and run it with Debug file. But it's not working. When I debug, this shows up in the Console:
c:\users\aycil\untitled5.py(1)<module>()
----> 1 def square(X):
2 print(x**2)

And when I write Square(3), it shows this in the Console:
Square(3)
*** NameError: Name 'square' is not defined


I can't solve the problem no matter what I do.
