The function below takes a single argument: data_list, a list containing a mix of strings and numbers. The function tries to use the Filter pattern to filter the list in order to return a new list which contains only strings longer than five characters. The current implementation breaks when it encounters integers in the list. Fix it to return a properly filtered new list.

    def filter_strings (data_list):

    string_list = []

    for s in data_list:

    if type (s) = = str and len (s) > 5:

    string_list. append (s)

    return string_list

    Explanation:

    Create a function called filter_strings that takes data_list as a parameter

    Initialize a new list to hold the strings that are longer than 5 characters

    Initialize a for loop that iterates through the data_list

    Check the elements if they are string - use type function, and if their length is greater than 5 - use len function. If an element satisfies the both conditions, put it to the string_list

    When the loop is done, return the string_list
