Modifying the Python range function

Question

I'm trying two variants of the python range function with the primary objective of making the function inclusive. However neither seems to be working

def main():
    for i in standard_range(1, 25, 1):
        print(i, end='')


def inclusive_range(*args):
    numargs = len(args)
    if numargs < 1:
        raise TypeError("Requires atleast one argument")
    elif numargs == 1:
        stop = args[0]
        start = 0
        step = 1
    elif numargs == 2:
        (start, stop) = args
        step = 1
    elif numargs == 3:
        (start, stop, step) = args
    else:
        raise TypeError("Cannot have more than three arguments")

    i = start
    while i <= stop:
        yield i
        i += step


def standard_range(start, stop, step):
    i = start
    while i <= stop:
        yield i
        i += step


if __name__ == " __main__ ":
    main()

Any help will be appreciated.

How are they not working? Provide expected output vs. current output. — Mark Tolonen

It works for me. Which is the problem? Maybe the problem is defining main function before standard_range — sharcashmo

No, the problem isn't the main() function's position. Since it isn't called until the other functions have been defined it won't cause any errors. But I agree it's confusing that the poster doesn't give expected vs. actual results. — holdenweb

If that is your exact code, main() won't run because you have spaces before and after __main__:

if __name__ == " __main__ ":
    main()

Remove the spaces:

if __name__ == "__main__":
    main()

standard_range should not print the stop value, so use < instead of <=:

while i < stop:

If I make those changes, and use this main:

def main():
    print(*standard_range(1,25,1))
    print(*inclusive_range(1,25,1))

The result is:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

Worked for me, the space thing. Thanks.
