为什么python脚本在Spyder vs cmd提示符下的工作方式不同

Question

I have the following script test.py :

import pathlib, os

path = "C:\\Windows"
pathparent = pathlib.Path("C:\\Windows").parent

if os.path.exists(pathparent):
    print("path exists")

and when I execute it in Spyder IDE I get this:

path exists

when I run it from the command prompt ( python test.py ) I get this:

Traceback (most recent call last):
  File "test.py", line 6, in <module>
    if os.path.exists(pathparent):
  File "C:\Anaconda3\lib\genericpath.py", line 19, in exists
    os.stat(path)
TypeError: argument should be string, bytes or integer, not WindowsPath

Any idea why I get the different results?

Note: I know that wrapping pathparent in str() will make the if statement succeed, but what I want to know is why the the two environments yield different results.

os.path.exists()开始在Python 3.6中接受路径对象，并且您的问题在运行Python 3.5的cmd提示中出现，请将其更改为3.6以解决您的问题。
