Today I´m talking about lists, as I mention in a previous post, a list is a group of items that have a position. The syntax of the lists is like it follows:
name_of_the_list = [elements,elements]
The positions start at 0 and you call them like this
name_of_the_list [0]
Also you can modify them just calling the position and making it equal to the new value
list1[0]: physics
or delete elements writing del before the position
del list1[2];
Also you´re able to do the basic operations
| Python Expression | Results | Description |
|---|---|---|
| len([1, 2, 3]) | 3 | Length |
| [1, 2, 3] + [4, 5, 6] | [1, 2, 3, 4, 5, 6] | Concatenation |
| [‘Hi!’] * 4 | [‘Hi!’, ‘Hi!’, ‘Hi!’, ‘Hi!’] | Repetition |
| 3 in [1, 2, 3] | True | Membership |
| for x in [1, 2, 3]: print x, | 1 2 3 | Iteration |
