[Solution]PermissionError: [Errno 13] Permission denied:

Writing Python engineering code took me 5 hours to troubleshoot, and finally found out that the permission was not enough when writing to the file. .

I do a test:

Write a file to the root directory of drive C:

a = "C:\\日志_test.txt"
with open(a, 'w', encoding='utf-8') as file_object:
    file_object.write(a)

Error after running:

D:\Code\check_tool\venv\Scripts\python.exe D:/Code/check_tool/222.py
Traceback (most recent call last):
  File "D:/Code/check_tool/222.py", line 2, in <module>
    with open(a, 'w', encoding='utf-8') as file_object:
PermissionError: [Errno 13] Permission denied: 'C:\\日志_test.txt'

进程已结束,退出代码1

Then I changed the C in the source code to D:

a = "D:\\日志_test.txt"
with open(a, 'w', encoding='utf-8') as file_object:
    file_object.write(a)

No more errors after running:

D:\Code\check_tool\venv\Scripts\python.exe D:/Code/check_tool/222.py

进程已结束,退出代码0

I was also drunk. . .

Therefore, if you write files in Python, you must consider the invisible problem of system permissions.
