I have a perl script which calls a python function with an array as an argument. The python function needs to loop through the array elements. I tried below, but the python function reads the array as string.

my @stmts = ("cd /tmp", "touch test.txt") python.exe test.py @stmts

Python

def test(stmts) print("Statements:" stmts)

I want to read stmts as a list in python. Any help on this is greatly appreciated. Thank you.

Arguments can only be strings. You can't pass an array. But since you have an array of strings, you can pass the strings as individual parameters.

system("script.py", @stmts);

They will be present as a list in sys.argv[1:].

stmts = sys.argv[1:]

For more complex structures, you will need to serialize and deserialize the data somehow. JSON is common choice, but many other options exist.

You can't pass an array to python from outside. It will be read as a string. You can convert the string to an array in your python code.

a = '["x","y","z"]'
print(a.replace("[",'').replace("]",'').replace('"','').split(','))
['x', 'y', 'z']

If you have parenthesis and quotes as part of the string then you will have to replace it. If you have just a string like 'x,y,z' the you can just do spilt(',') to get an array.
