sys.argv[0] always returns nothing [duplicate]

Question

I was trying to use sys.argv[0] to get the name of the script but it returned nothing. I guess that was because no script name was passed to the Python interpreter but I had no idea how to fix it.

my code:

import sys
print ("This is the name of the script: ", sys.argv[0])
sys.argv[0]

outputs:

>>> import sys
>>> print ("This is the name of the script: ", sys.argv[0])
This is the name of the script:
>>> sys.argv[0]
''

Thank you

Well, that's well expected,

you're running your code on the interpreter, which is not any module nor file, so sys.argv knows that and gives you an empty string.

It's a good sign.

If you run it in an actual module or file, it will work perfectly, as expected.
