python removing whitespace from string in a list

Question

I have a list of lists. I want to remove the leading and trailing spaces from them. The strip() method returns a copy of the string without leading and trailing

Answer 1

A much cleaner version of cleaning list could be implemented using recursion. This will allow you to have a infinite amount of list inside of list all while keeping a very low complexity to your code.

Side note: This also puts in place safety checks to avoid data type issues with strip. This allows your list to contain ints, floats, and much more.

    def clean_list(list_item):
        if isinstance(list_item, list):
            for index in range(len(list_item)):
                if isinstance(list_item[index], list):
                    list_item[index] = clean_list(list_item[index])
                if not isinstance(list_item[index], (int, tuple, float, list)):
                    list_item[index] = list_item[index].strip()

        return list_item

Then just call the function with your list. All of the values will be cleaned inside of the list of list.

clean_list(networks)
