→PART 2 - Command line arguments
print(len(sys.argv)) # tells us the number of command line arguments the user provide from a command shell
sys.exit() # will immediately end the running Python script, ignoring the remaining lines in the Python script
</source><br>Instead of using the '''input()''' function to prompt the user for data, we can use the list object '''sys.argv''' to capture the data item items provided at the command line when execution a Python scriptis being executed. The list object '''sys.argv''', when used within your Python script can store the following:<ul><li>'''sys.argv''' - stores all argument items as string objects</li><li>'''sys.argv[0]''' - stores the name of the script/program</li><li>'''sys.argv[1]''' - stores the first argument</li><li>'''sys.argv[2]''' - stores the second argument</li><li>etc...</li><li>'''len(sys.argv)''' - gives the number of arguments</li></ul><br>
