Python如何将阿拉伯数字转换化大写中文

Python将阿拉伯数字转换化大写中文是如何来实现的呢?下面的内容将会通过具体的实例来演示Python将阿拉伯数字转换化大写中文的实现方法及相关技巧:

周末在家,写了个小程序,用于将阿拉伯数字转换化大写中文。程序没经过任何优化,出没经过详细的测试,挂到网上,方便将来有需要的时候直接拿来用。

#!/usr/bin/python
#-*- encoding: utf-8 -*-
import types
class NotIntegerError(Exception):
pass
class OutOfRangeError(Exception):
pass
_MAPPING = (u’零’, u’一’, u’二’, u’三’, u’四’, u’五’, u’六’, u’七’, u’八’, u’九’, )
_P0 = (u”, u’十’, u’百’, u’千’, )
_S4, _S8, _S16 = 10 ** 4 , 10 ** 8, 10 ** 16
_MIN, _MAX = 0, 9999999999999999
def _to_chinese4(num):
”’转换[0, 10000)之间的阿拉伯数字
”’
