How can I call a variable inside a fuction to the outsides in Python?

August 1, 2023

I have this code:

import sys

x=0
y=0
z=0

def Total(a,b,c):
  a=1
  b=2
  c=a+b
  return c

Total(x,y,z)
print(z)

I initially anticipated a result of 3, but unfortunately, the outcome is still 0. How can I resolve this issue?

>Solution :

You need to assign the returned value of Total to z. Right now you aren’t doing anything with the returned value of Total(x,y,z).

x=0
y=0
z=0

def Total(a,b,c):
    a=1
    b=2
    c=a+b
    return c

Total(x,y,z) # Total returns 3, but the value is not assigned to anything
print(z) # Z is still 0

What you need is:

x=0
y=0
z=0

def Total(a,b,c):
    a=1
    b=2
    c=a+b
    return c

z = Total(x,y,z) # Assign the returned value of Total (which is 3) to z
print(z) # Print z (which is 3) out
