In python, How to append one list to another list?

append_a_list_to_list.md

You can append the new_options list to another list using the extend() method or the += operator. Here's how you can do it:

# Your new_options list
new_options = [
    {
        "shortname": "-clean",
        "help": "Cleans run directory",
        "required": True,
        "default": False,
        "datatype": bool
    }
]

# Another list to which you want to append new_options
existing_list = []

# Using the extend() method
existing_list.extend(new_options)

# OR using the += operator
# existing_list += new_options

print(existing_list)

Just replace existing_list with the name of the list to which you want to append new_options. Either the extend() method or the += operator will add the elements from new_options to the end of existing_list.
