Python for Everybody - Python Dictionaries
https://www.freecodecamp.org/learn/scientific-computing-with-python/python-for-everybody/pythondictionaries
What does dict equal after running this code?:
dict = {"Fri": 20, "Thu": 6, "Sat": 1}
dict["Thu"] = 13
dict["Sat"] = 2
dict["Sun"] = 9
{'Fri': 20, 'Thu': 6, 'Sat': 1}
{'Fri': 20, 'Thu': 6, 'Sat': 1, 'Thu': 13, 'Sat': 2, 'Sun': 9}
{'Sun': 9}
{'Thu': 13, 'Sat': 2, 'Sun': 9}
{'Fri': 20, 'Thu': 13, 'Sat': 2, 'Sun': 9}

Python for Everybody - Comparing and Sorting Tuples
https://www.freecodecamp.org/learn/scientific-computing-with-python/python-for-everybody/comparing-andsorting-tuples
Which does the same thing as the following code?:
lst = []
for key, val in counts.items():
newtup = (val, key)
lst.append(newtup)
lst = sorted(lst, reverse=True)
print(lst)
print( sorted( [ (v,k) for k,v in counts.items() ], reverse=True ) )
print( [ (k,v) for k,v in counts.items().sorted() ] )
print( sorted( [ (v,k) for k,v in counts.keys() ] ) )
print( [ (k,v) for k,v in counts.values().sort() ]
