Absolutely, let’s make it more comprehensive.
Demo Usage
To execute the code, navigate to the directory where the file is located or use the complete path to the file. The command below will invoke the function without displaying help documentation:
python reverse_string_with_docopt.py reverse
You will be prompted to enter the string to be reversed. After hitting enter, the function will display the reversed string.
For example, if you input the string Hello, World!
, the output will be:
!dlroW ,olleH
Here’s a screenshot showing the result after running the command and entering a string to be reversed:
Viewing Help Documentation
To view the reverse function’s help documentation, use the -h
or --help
options. These options provide users with guidance on how to use the script.
Run the following command to view the help documentation:
python reverse_string_with_docopt.py -h
The output will display the help documentation added to the top of the file. This includes details on the available commands and options.
Here’s an example of the help documentation displayed in the command line:
Using Quiet Mode
When the -q
option is invoked, it will display the current status of all options. This can be useful for debugging or understanding which options are active.
Run the following command to see the options status:
python reverse_string_with_docopt.py -q
The output will look like this:
{'--help': False,
'--quiet': True,
'--verbose': False,
'reverse': False}
Here’s a screenshot illustrating the output:
This example demonstrates how docopt simplifies the process of creating CLI documentation in Python, making your scripts more user-friendly and easier to understand. By following these steps, you can ensure your command-line tools are well-documented and intuitive for users.
