我有一个文本文件,其中包含文件路径列表,我想使用Python访问这些文件,然后将其复制并粘贴到新文件夹中。
const db = require("mongoose");
const User = require("./models/user");
router.post("/addusers", async (req, res, next) => {
const SESSION = await db.startSession();
await SESSION.startTransaction();
try {
const newUser = new User({
//*** data for user ***
});
await newUser.save();
//*** for test purpose, trigger some error ***
throw new Error("some error");
await SESSION.commitTransaction();
//*** return data
} catch (error) {
await SESSION.abortTransaction();
} finally {
SESSION.endSession();
}
});
所有文件都应复制并粘贴到新文件夹(output_folder)中。我该如何实现?
到目前为止,我的代码:
The file path list looks like this:
filepath1
filepath2
...
答案 0 :(得分:0)
我认为您可以使用shutil.copy函数来实现您的目标。会是这样的:
import shutil
import os
absolute_path = os.getcwd() # Stores original path.
os.makedirs("/output_folder") # Creates output_folder.
with open("filepaths.txt") as file:
for filepath in file.readlines():
path = filepath[:filepath.rfind("/")] # Extracts folder.
os.chdir(path) # Changes directory.
filename = filepath[filepath.rfind("/") + 1:] # Extracts filename.
filename = filename.replace("\n","") # Gets rid of newline character.
shutil.copy(filename, absolute_path + "/output_folder/")
如果出现PermissionDenied错误,请注释创建输出文件夹的行,并在工作目录中手动创建它。
