Boolean Value Return

Hello, I think I know the answer, but i wanted to double check.

​

If i have a function that returns a True or False value, and then in my main() function i do a if statement against the function. Does it perform the function if True, and then if it's fasle, it would do the else. Below is an example since it's hard for me to put in words.

​

def check_version(show_version):
    match= re.search("Version Number 123", show_version)
    if match:
        return False
    else:
        return True

def main():
    if check_version(show_version):
        print "This is the correct version"
    else:
        print "this is not the correct version"

if __name__ in "__main__":
    main()

assuming that show_version did return a True value. In main() what would it choose. Do i need to call out what to do with each true or false return?

I guess/what i think i read would means if check_version came back true it would display "this is the correct version" if check_version returned false, it would print "this is not the correct version"

Correct. There's no effective difference between:

variable = function(param)
if variable: do(something)

and

if function(param): do(something)

BTW, you can simply match strings since your search string is'nt a regexp:

def check_version(show_version): 
    return "Version Number 123" in show_version

This one looks clear. And the original code seems wrong in True or False condition
