random.choice(seq) Return a random element from the non-empty sequence seq. If seq is empty, raises

multiply(x, y) Return the product of x and y.

statistics.mode(data) Return the most common data point from discrete or nominal data. The mode (when it exists) is

random.normalvariate(mu, sigma) Normal distribution. mu is the mean, and sigma is the standard deviation.

shift(x, y) Returns a shifted copy of x, y times.

ln(context=None) Return the natural (base e) logarithm of the operand. The result is correctly rounded using the ROUND_HALF_EVEN

divmod(x, y) Divides two numbers and returns the integer part of the result.

rotate(other, context=None) Return the result of rotating the digits of the first operand by an amount specified by the second

statistics.pstdev(data, mu=None) Return the population standard deviation (the square root of the population variance). See

remainder_near(x, y) Returns x - y * n, where n is the integer nearest the exact value of x / y
