                问题描述

                我从 这里.

                f1 = open('file1.txt', 'r')
                f2 = open('file2.txt', 'w')
                for line in f1:
                    f2.write(line.replace('old_text', 'new_text'))
                f1.close()
                f2.close()
                

                但我不知道如何用各自的新词替换多个词.在这个例子中,如果我想找到一些像 (old_text1,old_text2,old_text3,old_text4) 这样的词并用它各自的新词替换 (new_text1,new_text2,new_text3,new_text4).

                But I am not able to figure out how to replace multiple words with respective new words. In this example if I want to find some words like (old_text1,old_text2,old_text3,old_text4) and replace by its respective new words (new_text1,new_text2,new_text3,new_text4).

                提前致谢!

                推荐答案

                你可以遍历你的检查词并使用 zip 替换词然后替换.

                You can iterate over your check words and toReplace words using zip and then replace.

                例如:

                checkWords = ("old_text1","old_text2","old_text3","old_text4")
                repWords = ("new_text1","new_text2","new_text3","new_text4")
                
                for line in f1:
                    for check, rep in zip(checkWords, repWords):
                        line = line.replace(check, rep)
                    f2.write(line)
                f1.close()
                f2.close()
