I've got some strings, which only contain numbers plus eventually one
character as si-postfix (k for kilo, m for mega, g for giga). I'm trying
to convert those strings to integers, with this function:
Why bother to always switch the case if you only use a few values?
Also, the Python style is to do an operation and handle failures, rather
than test first.
Try something like:
_units = dict(K=1000, M=1000000, G=1000000000,
k=1000, m=1000000, g=1000000000)
def eliminate_postfix(value):
try:
return _units[value[-1]] * int(value[: -1])
except (TypeError, KeyError):
return int(value)
If you normally do not have the suffixes, then switch it around:
def eliminate_postfix(value):
try:
return int(value)
except ValueError:
return _units[value[-1]] * int(value[: -1])
If this is really SI units, you likely are doing real measurements,
so I'd consider using "float" instead of "int" in the above.
