Question

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.

Answer 1

Screenshot of the code:

The function used is highlighted in grey color.

def filter_only_certain_strings (data_list): # Initialize an empty list new_list = [] for data in data_list: # string should be larger than 5 characters # hence put len (data) > 5 if type (data) == str and len(data) > 5: # append the elements in the new list which have length # greater than 5 new_list.append(data) # return new list return new list # printing the output print (filter_only_certain_strings (data_list=['abcdefghij','jkl',23897,' 123', '212','klul22', '678hjkl', 18910178, 212, 'ghjadgihnm', 'ewe', 8956782,' 567hdjdk']))

Sample Output:

['abcdefghij', 'klu122', '678hjkl', 'ghjadgihnm', '567hdjdk']

Code to copy:

def filter_only_certain_strings(data_list):

    # Initialize an empty list

    new_list = []

    for data in data_list:

       # string should be larger than 5 characters

       # hence put len(data) > 5

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

            # append the elements in the new_list which have length

            # greater than 5

            new_list.append(data)

    # return new_list

    return new_list

# printing the output

print(filter_only_certain_strings(data_list=['abcdefghij','jkl',23897,'123','212','klul22','678hjkl',18910178,212,'ghjadgihnm','ewe',8956782,'567hdjdk']))
