Python Argparse Guide: Command Line Parsing

argparse is a module in the Python standard library used for parsing command-line arguments, making it easier to create more flexible and powerful command-line tools. It allows us to easily define command-line arguments and options, and parse them from the command line.

The basic usage of argparse is as follows:

1. Use the library argparse
2. Create a parser object with a description of “description”.
3. Include a parser argument for the input ‘name’ with the corresponding help message.
4. Extract the arguments using the parser and store them in the variable “args”.
5. output the value of args.name

By adding different parameters and options, more complex command line tools can be achieved. argparse also supports setting the data type, default value, mutually exclusive options, subcommands, and other functions for parameters, allowing for flexible customization based on specific needs.
