👻 Check our latest review to choose the best laptop for Machine Learning engineers and Deep learning tasks!
I have an application, written in Python, which is used by a fairly technical audience (scientists).
I"m looking for a good way to make the application extensible by the users, i.e. a scripting/plugin architecture.
I am looking for something extremely lightweight. Most scripts, or plugins, are not going to be developed and distributed by a third-party and installed, but are going to be something whipped up by a user in a few minutes to automate a repeating task, add support for a file format, etc. So plugins should have the absolute minimum boilerplate code, and require no "installation" other than copying to a folder (so something like setuptools entry points, or the Zope plugin architecture seems like too much.)
Are there any systems like this already out there, or any projects that implement a similar scheme that I should look at for ideas / inspiration?

How to get an absolute file path in Python
3 answers
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? E.g. on Windows, I might end up with:
"C:/example/cwd/mydir/myfile.txt"
Answer #1
>>> import os
>>> os.path.abspath("mydir/myfile.txt")
"C:/example/cwd/mydir/myfile.txt"
Also works if it is already an absolute path:
>>> import os
>>> os.path.abspath("C:/example/cwd/mydir/myfile.txt")
"C:/example/cwd/mydir/myfile.txt"

How to check if a path is absolute path or relative path in a cross-platform way with Python?
3 answers
UNIX absolute path starts with "/", whereas Windows starts with alphabet "C:" or "". Does python have a standard function to check if a path is absolute or relative?
Answer #1
os.path.isabs returns True if the path is absolute, False if not. The documentation says it works in windows (I can confirm it works in Linux personally).
os.path.isabs(my_path)

How to join absolute and relative urls?
3 answers
I have two urls:
url1 = "http://127.0.0.1/test1/test2/test3/test5.xml"
url2 = "../../test4/test6.xml"
How can I get an absolute url for url2?
Answer #1
You should use urlparse.urljoin :
>>> import urlparse
>>> urlparse.urljoin(url1, url2)
"http://127.0.0.1/test1/test4/test6.xml"
With Python 3 (where urlparse is renamed to urllib.parse) you could use it as follow:
>>> import urllib.parse
>>> urllib.parse.urljoin(url1, url2)
"http://127.0.0.1/test1/test4/test6.xml"

I was preparing for my coding interview, thanks for clarifying this - Building a minimal plugin architecture in Python in Python is not the simplest one. Will use it in my bachelor thesis

Maybe there are another answers? What Building a minimal plugin architecture in Python exactly means?. I am just not quite sure it is the best method

Simply put and clear. Thank you for sharing. Building a minimal plugin architecture in Python and other issues with code Python module was always my weak point 😁. Checked yesterday, it works!
