Python List

In Python, the sequence of various data types is stored in a list. A list is a collection of different kinds of values or
items. Since Python lists are mutable, we can change their elements after forming. The comma (,) and the square
brackets [enclose the List’s items] serve as separators.
Although six Python data types can hold sequences, the List is the most common and reliable form. A list, a
type of sequence data, is used to store the collection of data. Tuples and Strings are two similar data formats for
sequences.
Lists written in Python are identical to dynamically scaled arrays defined in other languages, such as Array List in
Java and Vector in C++. A list is a collection of items separated by commas and denoted by the symbol [].
List Declaration
Code
1 # a simple list

2 list1 = [1, 2, “Python”, “Program”, 15.9]
3 list2 = [“Amy”, “Ryan”, “Henry”, “Emma”]
4
5 # printing the list
6 print(list1)
7 print(list2)

8
9 # printing the type of list
10 print(type(list1))
11 print(type(list2))
