def parse(text):
mo = re.match(r'(\d+)(\w?)', text)
if mo:

size = mo.group(2)
if size in units:
num *= 2**int(units[size])

return ValueError
return num
else:
raise ValueError
print parse('1B')
print parse('1kB')
print parse('1M')
print parse('1G')
print parse('1T')
print parse('1KB')
(Capital K isn't a proper prefix that I ever heard of.)
