Python library to create child processes and send STDIN and capture STDOUT

You know how tedious it becomes to continuously type input into the keyboard when you are just learning to program and your program is always asking you to enter input?

You know when you are writing a bunch of scripts and as you debug them you get sick and tired of always typing input into your keyboard when you should instead be focusing on debugging your script?

Welcome pySpawn.

Create a text file with your input you would normally type in the keyboard and tell pySpawn what script to run with which executable and that is it.

Example uses

Run a Python3 script using input from inputFile.txt.

from pyspawn import spawn

spawn.run_input_file("/home/levi/fil.py", "python3", "inputFile.txt")

...or a list of strings as input instead of a file

from pyspawn import spawn

spawn.run_input_list("/home/levi/fil.py", "python3", ["levi"])

It does not stop with just Python. Give pySpawn whatever executable you want and the input script and it does the rest. Here is Ruby.

from pyspawn import spawn

spawn.run_input_file("/home/levi/fil.rb, "ruby", "inputFile.txt")

Demo

1. Your input text file is a newline separated file like this one below: inputFile.txt

pySpawn is the best!

It is just a text file with some text in it.

2. Now lets create a script to run against pySpawn: runMe.py

output = input("hello there, what is your name? ")
print("Your name is: " + output)

3. Now create a script with the following code in it:

from pyspawn import spawn

output = spawn.run_input_file("runMe.py", "python3", "inputFile.txt")
print("Your program sent as output: " + output)

WOW! Now if you are debugging runMe.py for example in the future, just run this script and that is it. Go focus on what's more important then typing on your keyboard.
