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

A very simple solution would be:

SIZE_UNITS = ['B', 'KB', 'MB', 'GB', 'TB', 'PB']

def get_readable_file_size(size_in_bytes):
    index = 0
    while size_in_bytes >= 1024:
        size_in_bytes /= 1024
        index += 1
    try:
        return f'{size_in_bytes} {SIZE_UNITS[index]}'
    except IndexError:
        return 'File too large'
