first_counts This is a dict-count problem. Given a list of strings. We want to count the different chars that appear as the first char in a string. Return a counts dict with a key for every char that appears first in a string, and the value is the number of times it is the first char. Ignore empty strings (which do not have a first char). e.g. ['ax', '', 'bx', 'az', 'c'] returns {'a': 2, "b': 1, 'c': 1} Run code def first_counts(strs): first_nest This problem involves dict nesting. Given a list of non-empty strings. Create and return a "firsts" dict with a key for each first char among the strings. The value for each key should be a list of the strings with that first char in their original order, e.g. ['apple', 'bob', 'abe') returns {'a': ['apple', 'abe'], 'b': ['bob']} Run code def first_nest(strs): pass
