Lambda and filter in Python Examples
Prerequisite : Lambda in Python
Given a list of numbers, find all numbers divisible by 13.
Input : my_list = [12, 65, 54, 39, 102, 339, 221, 50, 70] Output : [65, 39, 221]
We can use Lambda function inside the filter() built-in function to find all the numbers divisible by 13 in the list. In Python, anonymous function means that a function is without a name.
The filter() function in Python takes in a function and a list as arguments. This offers an elegant way to filter out all the elements of a sequence “sequence”, for which the function returns True.
[65, 39, 221]
Given a list of strings, find all palindromes.
['geeg', 'keek', 'aa']
Given a list of strings and a string str, print all anagrams of str
