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.

Answer 1

Answer:

In Python:

def filter_only_str(mylist):

   for x in mylist:

       if isinstance(x, str) == False:

           mylist.remove(x)

   return mylist

Explanation:

The function is not given. So, I write from scratch.

In Python:

This defines the function

def filter_only_str(mylist):

This iterates through the list

   for x in mylist:

This checks if list item is not string

       if isinstance(x, str) == False:

If true that list item is not string, the item is removed from the list

           mylist.remove(x)

Return list

   return mylist
