python - How do you call a function in a function?

Question

I have a function and I'm making another one in which I need to call the first function. I don't have experience in Python, but I know that in languages like MATLAB it's possible as long as they're in the same directory.

A basic example:

def square(x):
    square = x * x

(and saved)

Now in my new function I want to use the function square I tried:

def something (y, z)
  import square
  something = square(y) + square(z)
  return something

Which displays: builtins.TypeError: 'module' object is not callable.

What should I do?

Answer 1

No need for import if its in the same file.

Just call square from the something function.

def square(x):
  square = x * x
  return square

def something (y, z)
  something = square(y) + square(z)
  return something

More simply:

def square(x):
  return x * x

def something (y, z)
  return square(y) + square(z)
