Hi guys...I'm baaaaack!
I have a list that contains listed tuples and inside of each tuple there is a dictionary.
I have to access the dictionaries and get the 'last_name' from all the records and use the Counter() function to return the number of occurrences for each last name. Where the output for example would be 'doe': 2, 'stark': 1 etc...
I have a result that works but for some reason when I define a function and add the code it gives me a totally different response.
Here we go....oh and one more thing...below is used to get the results from the function:
result = get_last_name_count(buckets)
for k, v in result.items():
print(f"{k}: {v}")
