Basically I want to write some script like

#!/bin/bash
for idx in 1 2 3 4 5 6
do
 echo machine$idx
 ssh machine$idx tmux new-session -d -s "myTempSession$idx" python run.py
done

which can do the thing separately as:

ssh machine$idx 

tmux new-session -d -s "myTempSession$idx"

python run.py

but after many trial and error, I still cannot make it work as expected.

UPDATE following Tagwint's advice, my script is:

#!/bin/bash
for idx in 1 2 3 4 5 6
do
 ssh machine$idx <<REMSH
 tmux new-session -d -s "myTempSession"
 tmux send-keys -t -s "myTempSession" python Space run.py C-m
 REMSH
done

but it prompts:

./dist_run.sh: line 8: warning: here-document at line 4 delimited by end-of-file (wanted `REMSH')
./dist_run.sh: line 9: syntax error: unexpected end of file

UPDATE I modify it to be

#!/bin/bash
for idx in 36 37
do
 ssh machine$idx <<REMSH
 tmux new-session -d -s "myTempSession"
 tmux send-keys -t -s "myTempSession" python Space run.py C-m
REMSH
done

this works, but after run the script, I log into machine36 and machine37, go into the opened myTempSession, the python run.py is not executed

I'd suggest you HERE-DOC apporach

ssh machine$idx <<REMSH
tmux new-session -d -s "myTempSession$idx"
tmux send-keys -t "myTempSession$idx" python Space run.py C-m 
REMSH

Note $idx part in session name will most probably resolve in nothing
unless you have a idx environment variable defined
so you'll get session name just myTempSession
