列表python2.7的maketrans替代方案

Question

INPUT = ["a","b","c","d","e","f","g","h","i","j","k"]
OUTPUT = ["20","21","22","23","24","25","26","27","28","29","30"]
TABLE = maketrans(INPUT, OUTPUT)
content = content.translate(TABLE)

TypeError: maketrans() argument 1 must be string or read-only character buffer, not list

我想要的是，例如，如果string=“a”，返回值为“20”。在

我不能将输入和输出转换成字符串，因为它们的大小不同。在

什么是最有效的选择或调整？在

Answer 1

使用izip_longest（Python 2.x）或zip_longest（Python 3.x）：

from itertools import izip_longest

INPUT = ["a","b","c","d","e","f","g","h","i","j","k"]
OUTPUT = ["20","21","22","23","24","25","26","27","28","29","30"]

string = 'a'   # string here

for i, o in izip_longest(INPUT, OUTPUT):
    if i == string:
        print(o)
# 20
