How can I insert certain python code using VIM input field?

Question

example:

fun! s:MyScript(startline,endline)

python3 << endpython
import vim

startline = vim.eval("a:startline")
endline = vim.eval("a:endline")

for n in range(startline, endline + 1):
    line = vim.current.buffer[n - 1]

#===========================
# start input lines

if re.search(...,line):
   do this or that

# end input lines
#===========================

    vim.current.buffer[n - 1] = line

endpython
endfun

I want to insert python code dynamically between start and end input lines in above script. I know that I can use Vim's input field (Let question = ....) to do certain things with "line" p.e. line = eval(myinputlline) but how can I insert python code like if re.search(....) and more lines at once?

@phd but what about the vim script? I still don't understand what you mean. — Reman

Instead of python3 << endpython you run py3file file.py. To change filenames at the execution time use execute: :execute 'py3file ' . filename. — phd

This works for me: file test-vim.py:

import vim

startline = vim.eval("line(\"'<\")")
endline = vim.eval("line(\"'>\")")

print(startline)
print(endline)

I started vim somefile. Selected a few lines from 6 to 3. Ran :py3file test-vim.py. vim reported
