Question

尝试替换文本文件中的子字符串时，其中每行引用双引号（＆＃34; line＆＃34;），如下所示：

" @user can't wait! love the orsen welles/citizen kane teaser reference in the promo vid!   positive"

此代码无效：

import re
with open(in_file, "r") as infile, open("Output.txt", "w") as outfile:
    for line in infile:
        #line = re.sub("@user", " ", line)        
        line = line.replace("@user"," ")
        outfile.write(line)

Output.txt文件包含与输入文件完全相同的行。怎么了？

链接到文本文件来源的存档：

要获取此文件，只需保存＆＃39; Manually-Annotated-Tweets.csv＆＃39;到文本文件。

输入和输出文件名不同。文件可以正常读取。尝试了几种不同的输出文件名。
