-Given a dictionary d and a list lst, remove all elements from the dictionary whose key is an element of lst. For example, given the dictionary {1:2, 3:4, 5:6, 7:8} and the list [1, 7], the resulting dictionary would be {3:4, 5:6}. Assume every element of the list is a key in the dictionary.

-Given three dictionaries, associated with the variables, canadian_capitals, mexican_capitals, and us_capitals, that map provinces or states to their respective capitals, create a new dictionary that combines these three dictionaries, and associate it with a variable, nafta_capitals.

-You are given a variable, wwII_battle_winners, that is associated with a dictionary that maps the names of World War II battles to the victors of WWII battles. Write some code that associates a sorted list of the battle names that appear as keys in this dictionary with the variable battles.

-Given the dictionary, d, find the largest key in the dictionary and associate the corresponding value with the variable val_of_max. For example, given the dictionary {5:3, 4:1, 12:2}, 2 would be associated with val_of_max. Assume d is not empty.
