How to use List Slicing In Python
Python allows us to do slicing inside a list. Slicing enables us to access some parts of the list. We can replace values inside the list using slicing. First, we find the index of variable that we want to replace and store it in variable ‘i’. Then, we replace that item with a new value using list slicing. Suppose we want to replace ‘Rahul’ with ‘Shikhar’ than we first find the index of ‘Rahul’ and then do list slicing and remove ‘Rahul’ and add ‘Shikhar’ in that place.
Syntax: l=l[:index]+[‘new_value’]+l[index+1:]
Python3
# Replace Values in a List using Slicing# define listl = ['Hardik', 'Rohit', 'Rahul', 'Virat', 'Pant']# find the index of Rahuli = l.index('Rahul')# replace Rahul with Shikharl = l[:i]+['Shikhar']+l[i+1:]# print listprint(l) |
Output:
['Hardik', 'Rohit', 'Shikhar', 'Virat', 'Pant']
