Which of the following statements are true? SELECT ALL THAT APPLY A dictionary is not iterable. If die is a dictionary, dictionary returns a list of all the keys in the If my_dict is a dictionary, it can be sorted in ascending order of its keys using the dictionary's sort function. If my_dict is a dictionary, and k is a variable, the structure k in my_dict returns True if k is a key in the dictionary.

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...

Your program has a dictionary called classes. The keys in classes are teacher's last names (as strings), and the corresponding values are the number of students in that teacher's class. For example, if Mr. Brown has 17 students in her class, then 'Brown' might be a key in classes with a corresponding value of 17. Write a few lines in Python that will do the following: Ask the user to enter the last name of a teacher IF that last...
