How to run 2 python files from command line, one after another?

Question

An example is:

python script1.py arg1 arg2

python script2.py arg1

where arg1 is from the first python call

You can use `&&` to concatenate both commands https://stackoverflow.com/questions/5130847/running-multiple-commands-in-one-line-in-shell — F.Igor, Sep 07 '18 at 03:11
What do you mean by `where arg1 is from the first python call`, the input for second call is come from output of first call? — atline, Sep 07 '18 at 03:29

How does script1 return its result? If it’s in stdout, try:

python script2.py $(python script1.py arg1 arg2)

$(…) runs the first script and takes the stdout output as the argument for the second script.

preferably: `python script2.py $(python script1.py arg1 arg2)` – cdarke Sep 07 '18 at 06:49

It is a matter of taste, to use either $(...) or backticks, I like backticks more:

python script2.py `python script1.py arg1 arg2`
