这篇文章主要介绍了Python字节单位转换(将字节转换为K M G T),文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧

									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）
