Use the divmod function. SECONDS_PER_MONTH = 2629746 # 1/4800 of 400 Gregorian years def convert_seconds(seconds): "Return (months, weeks, days, hours, minutes, seconds)." months, seconds = divmod(seconds, SECONDS_PER_MONTH) minutes, seconds = divmod(seconds, 60) hours, minutes = divmod(minutes, 60) days, hours = divmod(hours, 24) weeks, days = divmod(days, 7) return months, weeks, days, hours, minutes, seconds def to_seconds(months, weeks, days, hours, minutes, seconds): return (((weeks * 7 + days) * 24 + hours) * 60 + minutes) * 60 + \ seconds + months * SECONDS_PER_MONTH >> convert_seconds(10**9) (380, 1, 1, 1, 28, 40) >>> to_seconds(*_) 1000000000 > or a bandwidth measure into megabits/s or gigabits/s or > megabytes/s or gigabytes/s, whatever's the most useful (ala df -h)? def convert_bytes(bytes): PREFIXES = ['', 'K', 'M', 'G', 'T', 'P', 'E', 'Z', 'Y'] x = bytes for prefix in PREFIXES: if x < 1024: return '%.4g %sB' % (x, prefix) x /= 1024. # No SI prefixes left, so revert to scientific notation return '%.3e B' % bytes >>> convert_bytes(40e9) '37.25 GB' >>> convert_bytes(2048) '2 KB' -- http://mail.python.org/mailman/listinfo/python-list
