Slicing trouble

My code seems to work but the tester replies that my code did not return the right values. I tested the code in workspace and it worked there. What is wrong with my code?

BR, Kimmo

PS I posted a question earlier related to a very similar situation in another coding challenge

slices.py 
def first_4(iterable):
    List = list(iterable)
    Slice = List[0:4]
    return ''.join(Slice)

Hi, Kimmo!

1 thing that you could change:

āž” Slices are basically parts of some object, so as long as the object you are slicing has an order (is iterable) you can slice it. This means you can slice lists, tuples and even strings! (You'll learn about tuples in just a few more courses). Anyway, here are a few examples.

str1 = "apple"

str1[0:2] # This will give me "ap"

list1 = ["hello", "my", "name", "is", "John"]

list1[0:4] # This will give me ["hello", "my", "name", "is"]

What does this mean?

This means that there is no need to convert the argument into a list. As long as the user passes in an iterable the function will work just fine!

Hope This Helps! If it does click the Up arrow!
