What is sys.argv? What does it contain? |
|
Answer» sys.argv is the list of command-line arguments passed to the Python program, argv contains all the items that come along via the command-line input, it’s basically an array holding the command-line arguments of the program. To use sys.argv, you will first have to import sys. The first argument, sys.argv[0], is always the name of the program as it was invoked, and sys.argv[l] is the first argument you pass to the program (here it is the C++ file). For example: main(sys.args[1]) Accepts the program file (Python program) and the input file (C++ file) as a list(array). argv[0] contains the Python program which is need not to be passed because by default _main_ contains source code reference and argv[l] contains the name of the C++ file which is to be processed. |
