converting arguments or input numbers

[Skaperen]

i've been doing things like this to convert arguments or input numbers:

   number = int(sys.argv[1])

now i have found a different way that is more fun though it needs more coding:

    try:
        number = eval(sys.argv[1])
    except:
        print('oops!')
        error_count += 1

if you want the traceback info, don't use the try/except. then you don't have to calculate formulas to enter their values (though you might have to use quotes around many formulas for most command shells).
