Post-install script with Python setuptools

Is it possible to specify a post-install Python script file as part of the setuptools setup.py file so that a user can run the command:

python setup.py install

on a local project file archive, or

pip install <name>

for a PyPI project and the script will be run at the completion of the standard setuptools install? I am looking to perform post-install tasks that can be coded in a single Python script file (e.g. deliver a custom post-install message to the user, pull additional data files from a different remote source repository).

I came across this SO answer from several years ago that addresses the topic and it sounds as though the consensus at that time was that you need to create an install subcommand. If that is still the case, would it be possible for someone to provide an example of how to do this so that it is not necessary for the user to enter a second command to run the script?

Answer #1

import time
time.sleep(5)   # Delays for 5 seconds. You can also use a float value.

Here is another example where something is run approximately once a minute:

import time
while True:
    print("This prints once a minute.")
    time.sleep(60) # Delay for 1 minute (60 seconds).

Answer #2

You can use the sleep() function in the time module. It can take a float argument for sub-second resolution.

from time import sleep
sleep(0.1) # Time in seconds

How do I delete a file or folder in Python?

Answer #1

os.remove() removes a file.
os.rmdir() removes an empty directory.
shutil.rmtree() deletes a directory and all its contents.

Path objects from the Python 3.4+ pathlib module also expose these instance methods:

pathlib.Path.unlink() removes a file or symbolic link.
pathlib.Path.rmdir() removes an empty directory.

Simply put and clear. Thank you for sharing. Post-install script with Python setuptools and other issues with http Python module was always my weak point 😁. I am just not quite sure it is the best method
