Help in writing a basic function

[meru120]

:I'm learning to write python code with a book, In the chapter about functions there is the following function example

def seven_eleven():
    x = 8
    y = 30
    return x, y


def main():
    var1, var2 = seven_eleven()
    print var1, var2

I tried to write the code but the output was "Process finished with exit code 0" instead of 8 and 30
?what did i do wrong

You need to call function main() to execute it. Add

main()

at the end of the program.
