Python 3.7.3 ''' Problem 3 Write a function called names, which takes a list of strings as a parameter. The strings are intended to represent a person's first and last name (with a blank in between). Assume the last names are unique. The function should return a dictionary (dict) whose keys are the people's last names, and whose values are their first names. For example: >>> dictionary = names([ 'Ljubomir Perkovic', \ 'Amber Settle', 'Steve Jost']) >>> dictionary['Settle'] 'Amber' >>>...

Python 3 Define a function below, get_subset, which takes two arguments: a dictionary of strings (keys) to integers (values) and a list of strings. All of the strings in the list are keys to the dictionary. Complete the function such that it returns the subset of the dictionary defined by the keys in the list of strings. For example, with the dictionary ("puffin": 5, "corgi": 2, "three": 3) and the list ("three", "corgi"), your function should return {"corgi": 2, "three"...

PYTHON 3: Write a function removeRand() that takes a dictionary d and an integer n as parameters. The function randomly chooses n key-value pairs and removes them from the dictionary d. If n is greater than the number of elements in the dictionary, the function prints a message but does not make any changes to d. If n is equal to the number of elements in d, the function clears the dictionary. Otherwise the function goes through n rounds in...

Python 3 Write a function named starCounter that takes three parameters: 1. a dictionary named starDictionary. Each key in starDictionary is the name of a star (a string). Its value is a dictionary with two keys: the string 'distance' and the string 'type'. The value associated with key 'distance' is the distance from our solar system in light years. The value associated with key 'type' is a classification such as 'supergiant' or 'dwarf'. 2. a number, maxDistance 3. a string,...

write a function firstLetterWords(words) that takes as a parameter a list of strings named words and returns a dictionary with lower case letters as keys. But now associate with each key the list of the words in words that begin with that letter. For example, if the list is ['ant', 'bee', 'armadillo', 'dog', 'cat'], then your function should return the dictionary {'a': ['ant', 'armadillo'], 'b': ['bee'], 'c': ['cat'], 'd': ['dog']}.
