Is it possible to specify the previous python directory?

I am trying to make the Python module for testing a script stand-alone in a directory for scalability and ease of maintenance.

I did some research and could not find the answer I'm looking for. Basically, I would like to determine if there is a function in Python that can do something similar to cd -in the shell.

I would usually like not to enter full path names and have all the paths relative to the given environment.

Example: I have my main directory where my scripts are located python-scripts, I have folders for each test environment demoand a folder from the screen for each test environment demo-screenshots.

If I wanted to save a screenshot to a screenshot from Python while working in a directory demo, I just send it to the directory below: demo-screenshotsusing the path '/demo-screenshots/example.png'. The problem is that I do not understand how to move the directory.

Thank.

Do you want to change the working directory? The python OS module has many features to help with this.

import os
os.chdir( path )

pathis ".."to go to one directory. If you need to check where you are before / after changing the directory, you can send the command getcwd():

mycwd = os.getcwd()
os.chdir("..")
#do stuff in parent directory
os.chdir(mycwd)     # go back where you came from

source 
path = os.path.dirname(__file__)
print(path)

will output a CWD file, say C: \ Users \ Test \ Documents \ CodeRevamp \ Joke

path2 = os.path.dirname(path)
print(path2)

will print the parent directory of the file: C: \ Users \ Test \ Documents \ CodeRevamp
