Options − This is the string of option letters that the script wants to recognize, with options that require an argument should be followed by a colon (:). Getopt.getopt(args, options, )Īrgs − This is the argument list to be parsed. Following is simple syntax for this method − This method parses command line options and parameter list. This module provides two functions and an exception to enable command line argument parsing. Python provided a getopt module that helps you parse command-line options and arguments. Kindly try to run these programs at your computer.Īrgument List: Īs mentioned above, first argument is always script name and it is also being counted in number of arguments. All the programs in this tutorial need to be run from the command line, so we are unable to provide online compile & run option for these programs. Print 'Number of arguments:', len(sys.argv), 'arguments.' Len(sys.argv) is the number of command-line arguments.
Sys.argv is the list of command-line arguments. The Python sys module provides access to any command-line arguments via the sys.argv. There are following three Python modules which are helpful in parsing and managing the command line arguments: Here Python script name is script.py and rest of the three arguments - arg1 arg2 arg3 are command line arguments for the program. The arguments that are given after the name of the Python script are known as Command Line Arguments and they are used to pass some information to the program. Python Command Line Arguments provides a convenient way to accept some information at the command line while running the program.
