同时运行多个python脚本，它们同时使用用户输入和while循环

Question

Basically I need to run three files simultaneously and independently. These files are started with a user input followed by an infinite While Loop.

I have found some questions similar to mine but the solutions do not quite fit my needs. I am still a beginner.

I have already tried:

python device1.py &
python device2.py &
python device3.py

I also tried doing this all in one file but the file is rather large and complicated, and have not succeeded thus far.

#some code that creates a csv

#input
device = input("input which device you want to connect to")

def function():
    #write to csv file from data

while True:
    #get live data from device

    #csv function
    function()

I expect to enter 3 inputs for my 3 scripts, they run their loops, I end the code and have 3 csv files.

Answer 1

Have you tried setting the input in your command?

echo inputForDevice1 | python device1.py &
echo inputForDevice2 | python device2.py &
echo inputForDevice3 | python device3.py &

Also remember to detach from the last python call ( python device3.py & ), otherwise you'll be stuck in the infinite loop.
