Map and Filter

Question

fill in the blanks to remove all items that are greater than 4 from the list

nums = [1, 2, 5, 8, 3, 0, 7]
res = list(filter(lambda x:x_5,__))
print(res)

Answer 1

res = list (filter(lambda x : x<5, nums))
print (res)

Answer 2

Hey friends here is an best example for filter I can give.
assume a list name fib = [0,1,1,2,3,5,8,13,21,34,55]
Now I want to remove all the even numbers from this list, using filters and lambda function
so my code is:
result = filter(lambda x: x % 2 == 0, fib)
now when I print the result, the output is:
print (result)
>> [0, 2, 8, 34]
This shows that the result is holding all the values that we wanted to remove.
Similarly in the given question we want numbers greater than 4 to be removed.
so similarly our result will be holding the values which are less than 5 and not greater than 4
so our code will be
res = list(filter (lambda x:x <5,nums))
print (res)

Here the Best Analogy that you can have is
having your own Subset from a Set.

Answer 3

um u want to remove all items greater than 4, so u filter numbers which are only smaller than 5, and then filter takes two arguments, the function and the list itself

Answer 4

Wow thanx it worked u are a legend

Answer 5

I filtered it but I don't know what to put in between the x's

Answer 6

hijos de puta

Answer 7

hi guys

Answer 8

nums = [1, 2, 5, 8, 3, 0, 7]
res = list(filter(lambda x: x5,nums))
print(res)

Answer 9

nums = [1, 2, 5, 8, 3, 0, 7]
res = list (filter (lambda x: x<5, nums))
print(res)

Answer 10

Fill in the blanks to extract all items that are less than 5 from the list.

nums = [1, 2, 5, 8, 3, 0, 7]
res = list(filter(lambda x: x<5:5,nums))
print(res)

Answer 11
