Pass Python list to bash/awk function

Question

I know that it is possible to call/insert Bash/awk commands/scripts within a Python script, I found something like os.system('''awk '[...]''') and I suppose it works as well just for bash commands. The question is, how is it possible to pass, for instance, a Python list to these commands/this script?

Why do you want to do this? It's usually unnecessary, error-prone and makes your script less portable. — daniel kullmann

Strictly speaking, you cannot. You need to produce a string from the list which the recipient can use. For example:

lst = ['one', 'two', 'three']
os.system("bash myscript.sh " + " ".join(lst)) #  bash myscript.sh one two three
