Step 1

random in python:-

A random number generator is a computational or physical device designed to generate a sequence of numbers or symbols that can not be reasonably predicted better than by a random chance. Random number generators can be true hardware random-number generators (HRNG), which generate genuinely unpredictable results, or pseudo-random number generators (PRNG), which generate results that look random, but are actually deterministic, and can be reproduced if the seed to the PRNG is known.
