Write a function roll_dice() that takes two arguments in this order: the number of rolls and the number of sides. This function should return a dict with the keys being the possible values for the die, and the values being the number of times that value came up, e.g. for 10 sides and 50 rolls, I might get { 1: 5, 2: 7, 10: 4, } Ensure that all possible die rolls have a corresponding key even if there were zero rolls recorded. Let's make a histogram. Write a function text_histogram () that accepts a one argument, a dict with integer values, and returns a string. For each key-value pair in the input dict, the output string should have a line containing the key, a colon character':', and a number of hashmarks corresponding to the key's associated value. These lines must be in numeric/lexicographic order by their key. Once you have that working, make sure the start of the hashmarks is consistent for each line. Make sure this function works with the roll_dice() function from the previous exercise, and that the label justification works for dice with >10 sides. Example: In [ ]: Out[ ]: histogram = text_histogram({'apple': 2, 'cat': 3, "banana': 2}) print (histogram) apple : ## banana: ## cat Hint: You can cast In [ ]: Out [ ]: : ### variable to a string with str(), e.g. num = 42 str (42) '42'
