#Create a program that will play the “cows and bulls” game with the user. The game works like this:
#Randomly generate a 4-digit number. Ask the user to guess a 4-digit number. For every digit that the user guessed correctly in the correct place, they have a “cow”. For every digit the user guessed correctly in the wrong place is a “bull.” Every time the user makes a guess, tell them how many “cows” and “bulls” they have. Once the user guesses the correct number, the game is over. Keep track of the number of guesses the user makes throughout teh game and tell the user at the end.

#Say the number generated by the computer is 1038. An example interaction could look like this:

#   Welcome to the Cows and Bulls Game! 
#   Enter a number: 
#   >>> 1234
#   2 cows, 0 bulls
#   >>> 1256

# Write a password generator in Python. Be creative with how you generate passwords - strong passwords have a mix of lowercase letters, uppercase letters, numbers, and symbols. The passwords should be random, generating a new password every time the user asks for a new password. Include your run-time code in a main method.

# Extra:

# Ask the user how strong they want their password to be. For weak passwords, pick a word or two from a list.

import random 

def password_generator():
  user_input = input("For a strong password, type 'strong'. For a weak one, type 'weak': ")

# Write a program (using functions!) that asks the user for a long string containing multiple words. Print back to the user the same string, except with the words in backwards order. For example, say I type the string:

#   My name is Michele
# Then I would see the string:

#   Michele is name My
# shown back to me.

# Write a program (function!) that takes a list and returns a new list that contains all the elements of the first list minus all the duplicates.

# Extras:

# Write two different functions to do this - one using a loop and constructing a list, and another using sets.

#Write a program that asks the user how many Fibonnaci numbers to generate and then generates them. Take this opportunity to think about how you can use functions. Make sure to ask the user to enter the number of numbers in the sequence to generate.(Hint: The Fibonnaci seqence is a sequence of numbers where the next number in the sequence is the sum of the previous two numbers in the sequence. The sequence looks like this: 1, 1, 2, 3, 5, 8, 13, …)

#Keep track of how many guesses the user has taken, and when the game ends, print this out.
