@pombredanne : Output of github_release.py - https://github.com/Abhishek-Dev09/thirdparty/releases/tag/v1.0 . It is automated and generated by this script only . Now i focussing for py3.6 for now. So don't panic for py 3.7 & 3.8 . Once we done with 3.6 , we can easily move to other py version.

Thanks!
I posted some comments for a start.

I think you need to design some Requirements object (see dparse or packaging or pyup for libraries that may be worth adopting such as https://github.com/pyupio/pyup/blob/master/pyup/requirements.py ) and not read/write continuously to files with hardcoded names.

+import subprocess

+os.chdir(os.pardir) #go to etc


Why not keeping this in a function?

+os.chdir(os.pardir)  # go to scancode-toolkit
+cwd = os.getcwd()
+print("Current working directory:", cwd) 
+fp = open("requirements.txt", "wb")


Why do you open/close here? It does nothing and is possibly a source of failures

It create empty file . We need that because without this this scripts not work. This script assume that we already have requirements.txt file.

Can you use .format() with a mapping? It makes things much easier to read

You need to use single vs. double quotes consistently. We use single quotes unless this is a doc string.

Please do it everywhere.

+        for line in read_obj:


Can you find a better name than read_obj

i use name as file

Yes, but find a better name: read_obj means nothing. What is this file about? what does it contain?

Could you craft some kind of object for the requirements like some Requirement class and not open the requirements.txt file over and over?
Also the file may very likely be named some else than requirements.txt?

In open("requirements.txt", 'r') use instead open('requirements.txt') as reading text is the default alright.

Thank you! here are some comment for your consideration:

Can you review and fix the formatting for your code?
Having an a Requirement object of sorts would really make more sense that always opening and writing a file.
Please do not mix adding or removing wheels in this PR, focus instead on the scripts only
you need to add also tests

You should accept an argument with a path to a requirements files instead of trying to change the working dir.

Use a with context manager.

You should accept an argument for the thirdparty directory. Also it would be likely easier to understand if you load all file paths at once and iterate after. You should also reuse the commonode.fileutils functions

You talking about which function in fileutils?

resource_iter()

I would really prefer that you use that https://github.com/jwodder/wheel-filename as a library.

Do not do that. Have a requirements file instead and a README.rst that explains what to do

do not use input, instead use arguments for main() and accept command line arguments

which filename would ever start with "py2-"? and what is endswith(".gz")? about?

py2-ipaddress.tar.gz

Why would you single out a specific package name? What's so special about this?

because my function would not work for py2-ipaddress.tar.gz but don't worry this package will be removed after dropping python 2.

your function should not have any Python-package specific hack. The problem is in your code then

@Abhishek-Dev09 can you check your ABOUT files?

You need to be properly configured with ./configure ... if you ran it once about would be there
