如何使用Atom编辑器在Python中将脚本的路径设置为工作目录？

Question

I want to set the path of the python script as the working directory. I've tried the solutions I've found other solutions, but they aren't working for me.

This solution:

import os

path = os.path.dirname(os.path.realpath(sys.argv[0]))
dn = os.path.dirname(os.path.realpath("__file__"))
dn

gives:

'C:\\Users\\23392\\Desktop'

and my script is in a folder of desktop.

This solution:

import os
print(os.path.dirname(os.path.realpath(__file__)))

gives the following error:

NameError: name '__file__' is not defined

I need to define it as a string to prevent the error. And I get the same result that the previous one:

'C:\\Users\\23392\\Desktop'

The path should be:

C:\Users\23392\Desktop\05_Work\test.py

EDIT

I've found a partial solution. If I open the file with right click->open with->Atom, it recognizes the path of the file. It works this way but it has to be another way to do it.

Answer 1

Please try this version:

import os

abspath = os.path.abspath(__file__)
basename = os.path.basename(__file__)
fullpath = os.path.join(abspath + "\\" + basename)

print(fullpath)

Write this code into a file and then run it using Python interpreter.

If you try it from an interactive shell it will not work, __file__ is not defined in the interactive interpreter because it is meaningless there.

It is set by the import implementation, so if you use a non-standard import mechanism it might also be unset.
