这个代码实现的是利用Jaro distance来进行选择最有的匹配对象,而事实上这个方法经测验并不是十分的精准,如果你想更佳精准(同样会丢失一些相似的对象)的方法,soundex是更好的方法,大致上来说,soundex根据发音对于每个string进行编码,如果编码相同则表示两个字符完全相似,具体实现方法和我所写的代码差不多,在这里不再赘述。
现在用 left 的方式进行 merge。 df_1 = pd.DataFrame({"userid":['a', 'b', 'c', 'd'],"age":[23, 46, 32, 19]})df_2 = pd.DataFrame({"userid":['a', 'c','e'],"payment":[2000, 3500, 600]})pd.merge(df_1, df_2,how='left', on="userid")#userid age payment...
