我就废话不多说了，直接上代码！
from enum import Enum
class Values():
values={'B':1}
@staticmethod
def getValues():
if len(Values.values)<=1:

for index,unit in enumerate(kibunits):
Values.values[unit]=1<<(index+1)*10
for index,unit in enumerate(kbunits):
Values.values[unit]=10**((index+1)*3)
return Values.values
@staticmethod
def get(key):
return Values.getValues().get(key)
class Units(Enum):

obj = object.__new__(cls)
print (name)
obj._value_=Values.get(name)
return obj

以上这篇Python字节单位转换实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持脚本之家。
