Question

尝试对某些文件批量运行正则表达式。

正则表达式代码：

我正在运行的其他代码并出现错误

f=open("filenames.txt")
for filename in f:
   file=open("C:/Users/User/Desktop/toate/"+filename)
   text=file.read()
   valuesHextractor(text)
   file.close()
f.close()

filenames.txt包含列表中存在的文件名文件夹。
包含文件的文件夹的路径为：C：/ Users / User / Desktop / toate /

它成功地从filenames.txt中提取了文件名并将其添加到路径中，但是请注意，最后它添加了 \n ，我不知道它在哪里来自，使用以下错误破坏我的代码：

== RESTART: C:/Users/User/AppData/Local/Programs/Python/Python37-32/go.py ==
Traceback (most recent call last):
  File "C:/Users/User/AppData/Local/Programs/Python/Python37-32/go.py", line 3, in <module>
    file=open("C:/Users/User/Desktop/toate/"+filename)
OSError: [Errno 22] Invalid argument: 'C:/Users/User/Desktop/toate/AANICAGHEORGHE.doc\n'
>>>

我在做什么错了？

Answer 1

f=open("filenames.txt")
for filename in f:
    filename = filename.strip("\n")
    file=open("C:/User/User/Desktop/toate/"+filename)
    text=file.read()
    valuesHextractor(text)
    file.close()
f.close()

您可以像这样轻松地将其剥离。或

filenames = [i.strip("\n") for i in open("filenames.txt").readlines()]

编辑：\n是filenames.txt文件结尾的行。当计算机将文件存储到存储器中时，它用于标记行尾。

Edit2：示例用法

filenames = [i.strip("\n") for i in open("filenames.txt").readlines()]
for filename in filenames:
    file=open("C:/User/User/Desktop/toate/"+filename)
    text=file.read()
    valuesHextractor(text)
    file.close()
f.close()
