Hello, could anyone help me with this task

Question

I'm trying to do this test task

If you are given a list of names, it should produce a list containing only names that consist of more than 5 characters.

You can check the length of a string using the len () function and use the filter () function to define the condition.

The thing is that I don't know how to use the len method in a lambda, and how to put the condition for the lambda start what the task wants. If anyone could help me with this I'll appreciate it.

Answer 1

A lambda is and acts like a function. It can accept arguments and return something.

There's an example in the tutorial about how to use lambda as aggregate in a filter() function. May you be inspired from the example

Answer 2

Ipang thank you, you're right, the problem is that I don't know how to incorporate the function (len) in the lambda in order for to do what the problem asked

Answer 3

Have you gotten it figured out now though? I think you only need to make the lambda return a boolean (True/False) value depending on the list element's length.

lambda ele: len( ele ) > 5

This lambda returns True when its argument's length was greater than 5

Answer 4

Thank you so much Ipang , your code worked, Jesús Crist bless you, thanks for the help

Answer 5

lt = [x for x in str(input('Enter Names: ')).split()]
print(list(filter(lambda i: len(i) > 5, lt)))

Answer 6

names = ["David", "John", "Annabelle", "Johnathan", "Veronica"]

result = list(filter(lambda x:len(x)>5,names))

print(result)
