# CODING EXERCISE # # Create a python class called KeywordTracker that tracks the occurrences of specific keywords. # It will require at least these methods: # # add_keyword: takes a string and adds it to the tracked keywords. # # track: takes a string, counts the occurrences of the specified keywords and returns an integer representing the # number of keyword instances in the string. # # results: returns a dictionary representing all keyword usage data. # # Here is an example of how it will be used and what the output should look like. # # >>> keyword_tracker = KeywordTracker('red', 'green') # # # >>> keyword_tracker.track('My favorite color is red.') # 1 # # >>> keyword_tracker.track('Red and green make yellow.') # 2 # # >>> keyword_tracker.track('The ball is blue.') # 0 # # >>> keyword_tracker.add_keyword('blue') # # >>> keyword_tracker.track('The American flag is red, white and blue.') # 2 # # >>> keyword_tracker.track('The sky looks extra blue today.') # 1 # # >>> keyword_tracker.results() # {'blue': 2, 'green': 1, 'red': 3} # Start your code here:
