Re: left padding zeroes on a string...

Your first conversion works fine. string1 = '32' string2 = "%04s" % (string1) print string2 ' 32' Notice that it returns a string with spaces padding the left side. If you want to pad a number with 0's on the left you need to use zfill() '32'.zfill(4) '0032' Be sure to study up on string methods,
