Py: 6. Python Lists

A list in Python is used to store the sequence of various types of data. Python lists are mutable type its mean we can modify its element after it created. The items in the list are separated with the comma (,) and enclosed with the square brackets [].

Syntax:-

L1 = ["Mohit", 102, "INDIA"]   

List Indexing and Slicing

The indexing is processed in the same way as it happens with the strings. The elements of the list can be accessed by using the slice operator [].

The index starts from 0 and goes to length - 1. 

Example:- 

list = [1,2,3,4,5,6,7]  

print(list[0])  

print(list[1])  

print(list[2])  

print(list[3])  

# Slicing the elements  

print(list[0:6])  

# By default the index value is 0 so its starts from the 0th element and go for index -1.  

print(list[:])  

print(list[2:5])  

print(list[1:6:2])  

Output:- 

1

2

3

4

[1, 2, 3, 4, 5, 6]

[1, 2, 3, 4, 5, 6, 7]

[3, 4, 5]

[2, 4, 6]
