从相对于当前文件的路径获取绝对值

Posted 2021-02-24

Sometimes (ex. django templates section at setting.py), a function expects an absolute path, but it's more practical when developing to refer it to the current file position in our code base. The rel function does exactly that.

import os 
def rel(*x):
    return os.path.normcase(os.path.join(os.path.dirname(__file__), *x))
