How can I call Vim from Python?

Question

I would like a Python script to prompt me for a string, but I would like to use Vim to enter that string (because the string might be long and I want to use Vim's editing capability while entering it).

Answer 1

You can call vim with a file path of your choice:

from subprocess import call
call(["vim","hello.txt"])

Now you can use this file as your string:

file = open("hello.txt", "r")
aString = file.read()
