I am sort of newer to python and I can’t understand why my parameters aren’t defined. I’m not understanding why parameters aren’t global when I call the global function to the parameters, it says its already global. Here’s the code

def Forum(Age, Sex, BirthYear):
    Age,Sex,BirthYear = input('Enter the following:').split()
    print('What is your Age?',Age)
    print('What is your Sex?',Sex)
    print('What is your Birth year',BirthYear)

Forum(Age,Sex,BirthYear)

print('You are '+ Age +' Years old. You are '+ Sex +', and you were born in '+ BirthYear)

>Solution :

Wrong order. You seem to want this (with one input).

def Forum(Age, Sex, BirthYear):
    print('What is your Age?',Age)
    print('What is your Sex?',Sex)
    print('What is your Birth year',BirthYear)

Age,Sex,BirthYear = input('Enter the following:').split()
Forum(Age,Sex,BirthYear)

Or (with 3 separate inputs)

def Forum(Age, Sex, BirthYear):
    print('You are '+ Age +' Years old. You are '+ Sex +', and you were born in '+ BirthYear)

print('Enter the following:')

Age = input('What is your Age? ')
Sex = input('What is your Sex? ')
BirthYear = input('What is your Birth year? ')
Forum(Age,Sex,BirthYear)

This defines the variables for the function call itself; you are instead overriding your parameters within the function body, and making function-local variables, rather than global ones. You cannot define global vars within a function before they get used (by calling the function). Ex.

def SetAge(_age):
  print(_age)  # 2
  global age
  print(age)  # 0
  age = _age

age = 0
SetAge(int(input('What is your age? ')))  # inputs 2
print(age)  # prints 2
