Question1. Do you always have to convert a list to string to remove square brackets?
Main Question. I want to remove extra square brackets of a list nested in a list. The [] index of the nested list will change when the words change
Example
Words = ['Red Shirt', ['Minions', 'Expendables', 'Cannon Fodder']]
It looks like you're looking to flatten a list -- or the process of removing the "extra dimensions" of a list of lists down into a single dimension.
There's a lengthy discussion on in the thread linked here, but I have linked to my preferred solution https://stackoverflow.com/a/952952/9453914
Your solution will be a little different as you'll first need to add a few more brackets to make your life a little easier, however, this should work for the example given above
Words = ['Red Shirt', ['Minions', 'Expendables', 'Cannon Fodder']]
words = [[entry] if type(entry) == str else entry for entry in Words ]
flattened = [word for l in words for word in l]
flattened
>>> ['Red Shirt', 'Minions', 'Expendables', 'Cannon Fodder']
Where we need to nest 'Red Shirt' in its own list first so flattening the entry doesn't start splitting the string into individual characters.
