Question

Given a path such as "mydir/myfile.txt" , how do I find the file's absolute path relative to the current working directory in Python?

(给定诸如"mydir/myfile.txt"类的路径，我如何找到相对于Python中当前工作目录的文件绝对路径？)

Eg on Windows, I might end up with:

(例如在Windows上，我可能最终得到：)

"C:/example/cwd/mydir/myfile.txt"

Answer 1

>>> import os
>>> os.path.abspath("mydir/myfile.txt")
'C:/example/cwd/mydir/myfile.txt'

(如果已经是绝对路径，也可以使用：)

>>> import os
>>> os.path.abspath("C:/example/cwd/mydir/myfile.txt")
'C:/example/cwd/mydir/myfile.txt'
