String utilities for stem

[atagar]

Hi Ravi, just pushed some new string utilities (mostly stolen from arm) to my 'str_tools' branch...

Looks good.

+  try:
+    time_sum = int(float(seconds))
+    time_sum += int(minutes) * 60
+    time_sum += int(hours) * 3600
+    time_sum += int(days) * 86400
+    return time_sum

If you don't mind importing datetime, that could be replaced with...

return datetime.timedelta(days=int(days), hours=int(hours), minutes=int(minutes), seconds=int(float(seconds))).total_seconds()

That is all.

+SIZE_UNITS_BYTES = (

+  (1024.0, " KB", " Kilobyte"),
+  (1.0, " B", " Byte"),

On OS X 10.6+, 1 kb = 1000 bytes, not 1024 bytes. Not sure if it'll break anything. Just, FYI - ​https://support.apple.com/kb/TS2419

Oh, neat. I didn't know that you could do that. I don't mind importing datetime, but personally I find the present summation to be a little bit easier to read than constructing a throwaway datetime object. But that's certainly debatable.

Thanks for the heads up. This won't break anything - this is simply a function for getting human readable labels and, frankly speaking, OSX is wrong about this.
