How can I run programs in tmux panes simultaneously?

I’m trying to make a script that opens up 4 tmux panes, and launch a python program inside of it. I want to do it simultaneously, but I don’t know how.

I tried

tmux new-session "python 'DogeClickBot (2)'/main.py $1 ; read" && tmux split-window "python LTCClickBot/main.py $1 ; read"

The first Python program launches, but not the second. Please help!
