Throw a dice
Let's create an infinite generator! Your task is to define the simulate_dice_throws() generator. It generates the outcomes of a 6-sided dice tosses in the form of a dictionary out. Each key is a possible outcome (1, 2, 3, 4, 5, 6). Each value is a list: the first value is the amount of realizations of an outcome and the second, the ratio of realizations to the total number of tosses total. For example (when total = 4):
{
1: [2, 0.5],
2: [1, 0.25],
3: [1, 0.25],
4: [0, 0.0],
5: [0, 0.0],
6: [0, 0.0]
}
Tip: use the randint() function from the random module (already imported). It generates a random integer in the specified interval (e.g. randint(1, 2) can be 1 or 2).
