Tuples are similar to Python lists, with one big difference: you cannot modify a tuple. You should only use tuples when you want a list to remain the same. If we wanted to add flavors to our ice cream flavors list above, a regular list would likely be better.

When would you use a tuple?

Tuples are used to store multiple items in a single variable. Tuple is one of 4 built-in data types in Python used to store collections of data, the other 3 are List, Set, and Dictionary, all with different qualities and usage. A tuple is a collection which is ordered and unchangeable.

When would you use a tuple vs a list?

Now that we know the differences between python tuples vs lists, it shouldn't be a very tough choice between the two. The major difference is that a list is mutable, but a tuple isn't. So, we use a list when we want to contain similar items, but use a tuple when we know what information goes into it.
