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. Here is a small program that returns the odd numbers from an input list:

# Python code to illustrate 
# filter() with lambda() 
li = [5, 7, 22, 97, 54, 62, 77, 23, 73, 61] 
final_list = list(filter(lambda x: (x%2 != 0) , li)) 
print(final_list) 

Output:

[5, 7, 97, 77, 23, 73, 61]
