Test time left: 14:31Choose the correct answerWhat is the output of the following program?import sysprint(len(sys.argv))
Solution
The output of the program will be 1.
Here's the step by step explanation:
-
The
sys.argvis a list in Python, which contains the command-line arguments passed to the script. -
With the help of
sys.argv, you can process command line arguments in Python. -
When you run a Python script,
sys.argv[0]is always the name of the script itself. -
If no additional command line arguments were passed when the script was run,
sys.argvwill contain only one item, the script name. -
Therefore, when you print the length of
sys.argvusinglen(sys.argv), it will output 1, because it only contains the script name.
