0 This one here is a list 1

and now it is a tuple so a tuple is just like a list but with parentheses not square brackets. 2

If you print it out of course you'd get the same representation as in here. 3

So (1, 4, 5) (1, 4, 5). 4

However the brackets and the parentheses is not the only difference between lists and tuples. 5

In fact this is just the difference in syntax. 6

The real difference there is that tuples such as this one in here are immutable and lists such as this 7

one 8

are mutable. 9

What that means is at the list monday_temperatures2 you can add more items to the list using for example 10

the append methods. 11

So if you check monday_temperatures too know you'll get a list mutated. This mutability makes this 12

very dynamic, you'll see you later how when we do this batch operations in each operation we are adding 13

items to the list as we generate those items those values with some functions. 14

But this is not the case with tuples. If you try to append in a tuple you'll get an error because the 15

tuple doesn't actually have an offensive method at all. 16

Likewise it doesn't have a remove method like the list does 17

so 4 is not there anymore, tuples however have the advantage that they are a bit faster than lists 18

but you should think what to use so whether to use lists or tuples you should think if the array you 19

are creating is going to be changed during the course of the program or not. 20

So for now I'm not going deeper into tuples and lists. 21

But when we create these 10 applications during the course you will understand the main differences 22

between the two by seeing how they work in the real programs.
