python實現將阿拉伯數字轉換成中文

第一種轉換方式:

1 --> 一 12 --> 一二def num_to_char(num): '''數字轉中文''' num=str(num) new_str='' num_dict={'0':u'零','1':u'一','2':u'二','3':u'三','4':u'四','5':u'五','6':u'六','7':u'七','8':u'八','9':u'九'} listnum=list(num) # print(listnum) shu=[] for i in listnum:# print(num_dict[i])shu.append(num_dict[i]) new_str=''.join(shu) # print(new_str) return new_str

第二種轉換方式:

1 --> 一 12 --> 十二 23 --> 二十三_MAPPING = (u’零’, u’一’, u’二’, u’三’, u’四’, u’五’, u’六’, u’七’, u’八’, u’九’, u’十’, u’十一’, u’十二’, u’十三’, u’十四’, u’十五’, u’十六’, u’十七’,u’十八’, u’十九’)_P0 = (u’’, u’十’, u’百’, u’千’,)_S4 = 10 ** 4def _to_chinese4(num): assert (0 <= num and num < _S4) if num < 20:return _MAPPING[num] else:lst = []while num >= 10: lst.append(num % 10) num = num / 10lst.append(num)c = len(lst) # 位數result = u’’for idx, val in enumerate(lst): val = int(val) if val != 0:result += _P0[idx] + _MAPPING[val]if idx < c - 1 and lst[idx + 1] == 0: result += u’零’return result[::-1]
