path - Visual Studio Code : FileNotFoundError: [Errno 2] No such file or directory

Question

当我通过 Visual Studio Code 加载文件时，VScode 找不到目录。

我可以在终端上毫无问题地运行代码，结果是:

young@young-desktop:/media/young/5e7be152-8ed5-483d-a8e8-b3fecfa221dc/text/mycodehtml/pracdl/golbin/TensorFlow-Tutorials/10_RNN/ChatBot$ python text_load_text.py 
['fij\n', 'feijfaef\n', 'ef\n', 'awef\n', 'awe\n', 'g\n', 'aweg\n', 'ae\n', 'wg\n', 'awe\n', 'h\n', 'aw\n', 'h\n', 'aw\n', 'ef\n', 'aweg\n', 'wea\n', 'gaw\n', 'eg\n', '\n']

但是使用 VScode:

young@young-desktop:/media/young/5e7be152-8ed5-483d-a8e8-b3fecfa221dc/text/mycodehtml/pracdl/golbin/TensorFlow-Tutorials$ cd /media/young/5e7be152-8ed5-483d-a8e8-b3fecfa221dc/text/mycodehtml/pracdl/golbin/TensorFlow-Tutorials ; env "PYTHONIOENCODING=UTF-8" "PYTHONUNBUFFERED=1" /home/young/anaconda3/bin/python /home/young/.vscode/extensions/ms-python.python-2018.6.0/pythonFiles/PythonTools/visualstudio_py_launcher.py /media/young/5e7be152-8ed5-483d-a8e8-b3fecfa221dc/text/mycodehtml/pracdl/golbin/TensorFlow-Tutorials 39707 34806ad9-833a-4524-8cd6-18ca4aa74f14 RedirectOutput,RedirectOutput /media/young/5e7be152-8ed5-483d-a8e8-b3fecfa221dc/text/mycodehtml/pracdl/golbin/TensorFlow-Tutorials/10_RNN/ChatBot/text_load_text.py

    with open('test.txt', 'r') as f:
FileNotFoundError: [Errno 2] No such file or directory: 'test.txt'

是什么导致了这个问题？

test.txt 文件原本打算位于 ./data/test.txt

所以我测试了

with open('./data/test.txt', 'r') as f:

但是VScode失败了

所以我尝试将 test.txt 文件移动到工作目录:

with open('test.txt', 'r') as f:

和

with open('./test.txt', 'r') as f:

但是所有的VScode都失败了。

Answer 1

首先通过os.path.dirname(__file__)获取当前运行的模块的目录.
然后，您可以将您的愿望文件的相对路径加入此目录路径。

from os.path import dirname, join
current_dir = dirname(__file__)
file_path = join(current_dir, "./test.txt")
with open(file_path, 'r') as f:
