How to pass a full String variable from shell script to python in one sys.argv

I would like to pass a String variable from Shell Script to my python script and have it stored in sys.argv[1].
Currently this is my situation:

main.sh

TEST="This is a test"
python main.py $TEST

main.py

if __name__ == '__main__':
     print(sys.argv[1])

result:

This

How do I send $TEST so that sys.argv[1] = "This is a test"?
I don’t want to have to reconstruct the String after sending it.

>Solution :

Edit your main.sh to following :

TEST="This is a test"
python main.py "${TEST}"

Variables need to expanded inside "" and will be transformed into its
value.
