​Let's solve tasks!

1. Generate Random Numbers: Generate a sequence of random numbers between a given range.

2. Simulate Coin Toss: Simulate a coin toss using the random function.

3. Randomize List Elements: Shuffle the elements of a list randomly.

4. Random Password Generator: Generate a random password with a given length.

5. Random Sample from List: Select a random sample of elements from a list.

6. Guessing Game Task:

Create a guessing game where the computer generates a random number between a specified range, and the player has to guess the number. The game should provide hints to the player, indicating whether their guess is too high or too low. The player should continue guessing until they correctly guess the number.
