在文件python中查找并替换多个单词 [英] find and replace multiple words in a file python

问题描述

我从此处.

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()

但是我不知道如何用相应的新词替换多个词.在此示例中，如果我想查找诸如(old_text1,old_text2,old_text3,old_text4)之类的词并将其替换为相应的新词(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).

提前谢谢！

推荐答案

您可以迭代检查字词，并使用zip替换字词，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()
