If I understand you, you've got your target text and you want to user to 
be given it so they can modify it, rather than having to retype it in 
full at the prompt.

On a UNIX system you'd use the standand "readline" module, and prefill 
the text buffer with your text. Is it marked as UNIX only, but I believe 
there are Windows dropins for this facility. Maybe install this package:

  https://pypi.org/project/pyreadline-ais/

maybe with "python -m pip install pyreadline-ais".

Then use it according to the documentation for the stdlib readline 
module:

  https://docs.python.org/3/library/readline.html#module-readline
