Hello Pankaj,

I cannot reproduce this.  Here's what I ran:

  $ emacs --version | head -1
  GNU Emacs 26.3
  $ emacs -Q -f package-initialize -L ~/path/to/eglot/eglot -l eglot \
    ~/path/to/a/python/file.py -f eglot

This opens the file which has your example contents, and starts up
eglot.  I move point to the end of line 2, press RET and press TAB
twice.  Point is at the left margin.

Without Eglot, the result is exactly the same.

I would find it odd that Eglot messes with TAB behaviour, but I'm
waiting for a more complete reproduction recipe from your part so we can
understand what's going on.

João
