我有两个DataFrames,我想根据列合并.然而,由于交替拼写,不同数量的空格,不存在/存在变音符号,我希望能够合并,只要它们彼此相似即可.

任何相似性算法都可以(soundex,Levenshtein,difflib).

假设一个DataFrame具有以下数据:

df1 = DataFrame([[1],[2],[3],[4],[5]], index=['one','two','three','four','five'], columns=['number'])

       number
one         1
two         2
three       3
four        4
five        5

df2 = DataFrame([['a'],['b'],['c'],['d'],['e']], index=['one','too','three','fours','five'], columns=['letter'])

      letter
one        a
too        b
three      c
fours      d
five       e

然后我想得到生成的DataFrame

       number letter
one         1      a
two         2      b
three       3      c
four        4      d
five        5      e
