CodePudding user response：

The syntax error is declared at line 17 but actually occurs at the end of line 16. You just need to close the parenthesis of the call of the function print. Also, the way you try to add the variables interface and new_mac in the string is incorrect; you need to use the format function.

Here is the code fixed:

[...]
def change_mac (interface, new_mac):
        print ("changing MAC ADDRESS FOR :{} to {}".format(interface, new_mac)) # FIXED
        subprocess.call(["ifconfig", interface, "down"])
[...]
