Question

Define a function below, filter_only_strs, which takes a single argument of type list. Complete the function so that it returns a list that contains only the strings from the original list and no other data. It is acceptable to return an empty list if there are no strings in the original list.

def filter_only_strs(1st):
for x in lst:
if isinstance(x,str)==False:
lst.remove(x)
return ist Restore original file

Answer 1

Step-by-step explanation:

The code provided aside from some minor errors (fixed version down below) is correct, but it will never be able to accomplish what is being asked in the question. This is because this code is simply copying and returning the exact same list that is passed as an argument, because it is looping through it and comparing its own elements. In order to accomplish what is asked in the question, two lists need to be passed as parameters. The first would be the original list, and the second would be a list of test elements that will be used to compare and see if they exist in the original list. This would allow us to create a new list with only the elements that existed in the original list.

def filter_only_strs(lst):

for x in lst:

if not isinstance(x, str):

lst.remove(x)

return lst
