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）

  if bytes < 1024: #比特
    bytes = str(round(bytes, 2)) + ' B' #字节
  elif bytes >= 1024 and bytes < 1024 * 1024:
    bytes = str(round(bytes / 1024, 2)) + ' KB' #千字节

  elif bytes >= 1024 * 1024 * 1024 and bytes < 1024 * 1024 * 1024 * 1024:
