In Python, the manipulating list also called arrays, is the main task while you are dealing or working with data. Stanford University in its Python tutorial added the below best examples.
Python List Commands
I am giving here for your reference. The hash given below is just a comment. It is not command.
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]
