Question

我正在尝试扫描目录和几个子目录下的所有文件中的字符串，替换它，当我执行替换时将其保存到新文件中，我成功了 1）在文件夹和子文件夹中的所有文件中搜索字符串， 2）计算字符串的出现量 3）为拥有该字符串的人创建新文件。

但由于某种原因，我得到的新文件是空的，而不是包含替换字符串的旧文件的行。

这是我的代码：

import os

parentDirectory = "E:\ProjectPython\Test"
oldString = "oldString"
newString = "newString"

if (os.path.isdir(parentDirectory)):
    for dirName,directories,files in os.walk(parentDirectory):
        for fileName in files:
            fullPath = os.path.join(dirName,fileName)
            with open(fullPath) as file:
                counter=0
                for line in file:
                    if line.__contains__(oldString) or line.__contains__(oldString.lower()):
                        counter=counter+1
                if counter>>0 :
                        with open(fullPath+".New","w") as newFile:
                            for line in file:
                                newFile.write(line.replace(oldString,newString))
                        print("File:"+fullPath+"\nStrings that were replaced:"+str(counter))

else:
    print(parentDirectory+"is missing!")

Python-Change String in file并将带有新字符串的所有内容输出到新文件
