Useful Commands to Create a List

Create a new list

empty = []
letters = [‘a’, ‘b’, ‘c’, ‘d’]
numbers = [2, 3, 5]

Lists can contain elements of different types

mixed = [4, 5, “seconds”]

Append elements to the end of a list

numbers.append(7)
numbers == [2, 3, 5, 7]
numbers == [2, 3, 5, 7]
numbers.append(11)
numbers == [2, 3, 5, 7, 11]

Access elements at a particular index

numbers[0] # => 2
numbers[-1] # => 11

Slice Lists rules to apply

letters[:3] # => ['a', 'b', 'c']
numbers[1:-1] # => [3, 5, 7]

Other Lists

x = [letters, numbers]
x # => [['a', 'b', 'c', 'd'], [2, 3, 5, 7, 11]]
x[0] # => ['a', 'b', 'c', 'd']
x[0][1] # => 'b'
x[1][2:] # => [5, 7, 11]
