Python format size application (converting B to KB, MB, GB, TB)

Question

I am trying to write an application to convert bytes to kb to mb to gb to tb. Here\'s what I have so far:

def size_format(b):
    if b < 1000:
              r         


        

Answer 1

When you divide the value you're using an integer divide, since both values are integers. You need to convert one of them to float first:

return '%.1f' % float(b)/1000 + 'KB'

or even just

return '%.1f' % b/1000.0 + 'KB'
