Python argparse arguments issue with passing strings containing hyphens

Title: Resolving Issues with Hyphenated Strings in Python Argparse Arguments
Python's argparse module is a powerful tool for parsing command-line arguments in a clean and organized manner. However, when dealing with strings containing hyphens, users may encounter issues due to the default behavior of argparse treating hyphens as option prefixes. This tutorial addresses this problem and provides a solution to pass strings containing hyphens as arguments.
Consider a scenario where you want to pass a string containing hyphens as an argument to your Python script. For example:
In this case, argparse will interpret John-Doe as an invalid option and raise an error.
To overcome this issue, you can use the nargs parameter of the add_argument method to specify the number of arguments an option should consume. By setting nargs to '+' or '*', you allow the option to accept multiple arguments, effectively treating the input as a list.
Let's illustrate this with an example:
In this example, the --name option is set to accept multiple arguments. Now, when you run the script with hyphenated strings:
By adjusting the nargs parameter in the add_argument method, you can successfully pass strings containing hyphens as arguments in Python scripts that use argparse. This provides a flexible solution for handling various types of input from the command line.
Remember to adapt the nargs value according to your specific needs, whether it's '+', '*', or any other suitable value based on your use case.
