I cannot understand this syntax error...

Question

I started to learn functions in Python; then when I used in main function in one of my assignments in my course.

The code is:

def func(num1, num2):
if num1 > num2:
return (num1 - num2)**2
return (num2 - num1)**2

def main():
num1 = 1
num2 = 2
print(func(num1, num2)

if __name__ == "__main__":
main()

and I get: "invaild syntax".

Answer 1

First you should clear about why are you want to add main in your code.
You should learn about main
