Thanks for the report.

I've tried reproducing this bug on the latest development branch and Emacs
26.2, but was unable to.

First, I have a file ~/foo.py with the following contents:

num = 200
print(num)

Next, I do this:

0. emacs -Q
1. M-x pdb RET pdb3 ~/foo.py RET

    Current directory is /home/skangas/
    > /home/skangas/foo.py(1)<module>()
    -> num = 200

2. Hit "n"

    (Pdb) n
    > /home/skangas/foo.py(2)<module>()
    -> print(num)

3. If I now do the step "C-x C-a C-p (in the python buffer) and C-c C-p (in
the
   > gud buffer)" (with point on the variable name), I see the following:

    num = 200
    num = 200
    (Pdb)

I don't see the message "Text is read only".

Are you still able to reproduce this bug on a recent version of Emacs?
If yes, could you please provide a recipe for how to reproduce it,
starting from "emacs -Q"?

If I don't hear back from you in a couple of weeks, I'll just assume
that the bug has been fixed in the years since you reported it and close
this bug report.

Best regards,
Stefan Kangas
