Question

我有一本txt格式的书。我想创建2个新文本：在第一个中，我想用"Paul"替换字符串Paul_1的所有出现，在第二个用Paul_2。我写了这段代码：

with open("book.txt", 'r') as original, \
        open("book_1.txt", 'w') as mod1, \
        open("book_2.txt", 'w') as mod2:
    for line in original:
        words = line.split()
        for word in words:
            s="Paul"
            if(word == s):
                mod1.write(word + "_1 ")
                mod2.write(word + "_2 ")
            else:
                mod1.write(word + " ")
                mod2.write(word + " ")
        mod1.write("\n")
        mod2.write("\n")

存在一个问题，通常会跳过一些Paul因此，最后，我在同一文档中同时包含Paul和Paul_1（以及Paul和Paul_2）。问题在哪里？

这应该有所帮助。

import re

with open("book.txt", 'r') as original, \
        open("book_1.txt", 'w') as mod1, \
        open("book_2.txt", 'w') as mod2:
    data = original.read()
    data_1 = re.sub(r"\bPaul\b", 'Paul_1', data)   #Replace any occurrence of Paul with Paul_1 
    data_2 = re.sub(r"\bPaul\b", 'Paul_2', data)   #Replace any occurrence of Paul with Paul_2 
    mod1.write(data_1 + r"\n")
    mod2.write(data_2 +  r"\n")
