To flatten a list of lists use list comprehension in Python, we can use a nestedforloop within the comprehension. The result is a one-liner that is both concise and efficient. It allows you to define a new list in a single line of code, without the need for explicit loops. In the ...
Flattening a List of Lists. Flattening a list of lists is a common task in Python. Let’s say you have a list of lists and need to flatten it into a single list containing all the items from these original nested lists. You can use any of several…
