I had a question about the 7th page of the “Cleaning and Preparing Data in Python” Mission.
def strip_characters(date): for b_char in bad_chars: clean_date = date.replace(b_char,"") return clean_date stripped_test_data =  for date in test_data: clean_test_data = strip_characters(date) stripped_test_data.append(clean_test_data)
It is saying that the value of the stripped_test_data is not what was expected. I don’t know what I’m doing wrong here. I used different variable names, however, they (I think!) seem to be in the correct places when I compare them to the answer from Dataquest.
