while loop not working

# I noticed a few issues with your code.
# First, you don't need print inside input, if you want to display something to do user and also capture their response
# this is how you would do it with input
user_input = input('What is your name')

# when you used print inside input it was returning None + whatever the user typed in the input
# thus it was not meeting the 'yes' value for the while loop to work
# That was the main reason why your  code wasn't working properly
# also I noticed that you were repeating your code, to be more specific this line:

add_player = input(print('Would you like to add a player to the list? (Yes/No)'))
another_player = input(print('Would you like to add another player? (Yes/No)'))

# If you look at the variable names you would notice that they are different, and
# the problem comes when you reach 'another_player'. What will happen is it will get the user's
# input but no matter what the user type it will still be in our while loop.
# The reason for that is our while loop test's if add_player.lower is == 'yes' and since
# we are not prompted to change the value of add_player it will keep looping and it will never stop
# Yes, we create another_player which will hold our value 'Yes/No', but this variable another_player
# is never tested in our while loop, thus making it pointless.
# The code below would work great in this scenario.
# First we will use a function to add_player(), which allows us to call the function whenever we want
# and we won't have repeating code. Then we will take the outcome of this function and test to see
# if it's == 'yes', if so it will go through and add a new 'name' for player to the players array.
# if you look at our while loop now you would notice that we are calling our function
# which will run again, prompting us whether we want to add player to our players' array, if we say 'no'
# it will update the add_player to 'no' thus making our condition in while loop false and exiting the application

# Here is the improved code, read over it and see the changes that I made
players = []

# def is used to define a function
# the function's name is add_player(), it asks the user whether they want to add a player
# if yes, ask for a name to be added into the players' array
# if no, the loop will no longer be true and the program will stop
def add_player():
    add_player = input('Would you like to add a player to the list? (Yes/No): ')
    # this return add_player will return the result of whatever the user typed, in this case, Yes or No
    return add_player

# Here we use add_player() function to test if the returned result is 'yes'.
# Once it runs once it will keep looping until we say 'no' when asked to add player

while add_player().lower() == 'yes':

    name = input('Enter the name of the player: ')

    players.append(name)

    # Shows the players in the array
    print(players)

# Your problem is here
answer = print(int(input('Guess a number between 1 and 10: ')))

# You don't need the print() there,
# input() will automatically print whatever is inside the quotes, 'Guess a number between 1 and 10: '
# You get the TypeError because of print(), in this case, print() will return None
# because it's interfering with input(''). To fix it just remove print(), like this

answer = int(input('Guess a number between 1 and 10: '))

import random

# This will keep track of how many times we guessed a number
guesses = 0
# Default value for answer
answer = 0

# Here we set a default start and end Number, this will allow you to scale your code better
# all you need to do is edit these 2 number to scale the guess numbers
startNumber = 1
endNumber = 10

# It's easier to call print(conditions[0]) rather than print("It's higher. Try Again: "), you can change it if you don't like it
conditions = ["It's higher. Try Again: ", "It's lower. Try Again: ", "The number is outside the range"]

print('Welcome to the game!')

# To make the game more exciting why not randomize the number
# this will hold our magical number which we would have to guess
magicNumber = random.randint(startNumber, endNumber)

# Basic function that allows us to test whether our guess number is lower or higher than the magic number
def numberGuesser():
    if answer > endNumber or answer < endNumber: print(conditions[2])

    if answer < magicNumber and answer >= startNumber: print(conditions[0])

    if answer > magicNumber and answer <= endNumber: print(conditions[1])

# This allows us to avoid creating an else statement on if statements
# it basically will exit out of the while loop when answer == magicNumber
while answer != magicNumber:
    # We should always account for users input. Since this is a number guesser, there shouldn't be any letters when
    # we are guessing the magic number therefore we should wrap our logic in try except to handle errors
    # If you look at the answer, it takes an int from the input but what will happen if the user enters a letter
    # it will throw a ValueError and it will break your code, but we don't want that to happen.. so try except is
    # the way to go
    try:
        # This updates how many times the user tried to guess the number
        guesses += 1

        # Here we take the user's input
        answer = int(input('Guess a number between {} and {}: '.format(startNumber, endNumber)))

        #And here we run our function which tests our answer against the magicNumber
        numberGuesser()
    # This is where we handle the ValueError
    # The following code will run only if the user enters a non numeric number
    except ValueError:

        print('\nPlease enter a number between {} and {}'.format(startNumber, endNumber))

# This will show only when the user guessed the magicNumber
print('You got it!\nIt took you {} attempts to get to the correct answer'.format(guesses))
