How to use Lambda Function In Python
In this method, we use lambda and map function to replace the value in the list. map() is a built-in function in python to iterate over a list without using any loop statement. A lambda is an anonymous function in python that contains a single line expression. Here we gave one expression as a condition to replace value. Here we replace ‘Pant’ with ‘Ishan’ in the lambda function. Then using the list() function we convert the map object into the list.
Syntax: l=list(map(lambda x: x.replace(‘old_value’,’new_value’),l))
Python3
# Replace Values in a List using Lambda Function# define listl = ['Hardik', 'Rohit', 'Rahul', 'Virat', 'Pant']# replace Pant with Ishanl = list(map(lambda x: x.replace('Pant', 'Ishan'), l))# print listprint(l) |
Output:
['Hardik', 'Rohit', 'Rahul', 'Virat', 'Ishan']
