Python字节单位转换(将字节转换为K M G T)

def bytes_to_human(n):
  symbols = (\'K\',\'M\',\'G\',\'T\',\'P\',\'E\',\'Z\',\'Y\')
  prefix = {}
  for i,s in enumerate(symbols):
    prefix[s] = 1 << (i + 1) * 10
  for s in reversed(symbols):
    if n >= prefix[s]:
      value = float(n) / prefix[s]
      return \'%.1f%s\' % (value,s)
  return \'%sB\' % n

python编写的储存单位转换代码（以字节(B)为单位）
