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
”’
assert(0 <= num and num < _S4) if num < 10: return _MAPPING[num] else: lst = [ ] while num >= 10:
lst.append(num % 10)
num = num / 10
lst.append(num)
c = len(lst) # 位数
result = u”
for idx, val in enumerate(lst):
