如何获取导入的python文件的绝对路径

Question

I have following code structure:

config_dir
    config.py

main.py

There is a method in config.py as follows:

def get_path():
    # TODO 
    return "the absolute path of config.py, not the path of the main.py that import this config module"

in the main.py, I import the config module and call config's method get_path

from config_dir import config

print(config.get_path())

I would like print the absolute path of config.py, not the path of the main.py that import this config module

I would like how to code this, thank!

Answer 1

You can use file to get absolute path for imported module. For example:

from config_dir import config

print(config.__file__)

>>> import datetime
>>> datetime.__file__
'/usr/local/Cellar/python@2/2.7.17/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/datetime.so'
>>> 

Answer 2

You can use this:

import os

def get_path():
    return os.path.abspath(__file__)

Answer 3

Try the following code:

import os
os.path.abspath(config)

Add the following code in config.py

import os

def get_path():
    return os.path.abspath(__file__)
