Answers
Answer:
I think the correct answer is
(A) main(sys.argv[1:))
(A) main(sys.argv[1:])
- This is a function call statement which calls the main() function and passes a list of command line arguments to it.
- The sys.argv[1:] argument in this statement is a slice of the sys.argv list starting from index 1, which excludes the first element of the list (the name of the script file) and returns all the remaining elements as a new list.
- The main() function will then process these command line arguments as required.
The explanation of all options: -
(B) main
This is not a function call statement. It is a string that is used in the if __name__ == '__main__': statement to check whether the current module is being run as the main program. The __name__ variable contains the name of the current module, and if its value is '__main__', it means that the module is being run as the main program.
(C) name
This is not a function call statement. It is a variable that is used in the if __name__ == '__main__': statement to check whether the current module is being run as the main program. The __name__ variable contains the name of the current module, and if its value is '__main__', it means that the module is being run as the main program.
(D) argy
This is not a valid Python variable name, and it is not used in the given code snippet.
