Error with a player turn ending loop in the Zombie Dice game

I'm trying to develop a code for the zombie dice game.
My problem is when the first player replies that he doesn't want to continue playing.
The game ends and I can't get the second player to play. Can someone help me?

Does anyone know what I'm doing wrong?
I'm new as a programmer. If anyone knows how to help me with this problem, I would be grateful.

EDIT: Well now the code just works. I can switch players just fine, but if you go through all the characters it crashes again since jogadorAtual gets too big for listaJogadores. I don't quite understand the game, but assuming you want to start back with the first player, an elegant way you can accomplish that is by doing modulus with the % operator, which divides two numbers but returns the remainder. If you divide the number of players by the size of listaJogadores, you'll always get a number inside listaJogadores's range.
# Change this...
print("PLAYER TURN: ", listaJogadores[jogadorAtual])
# ...to this
print("PLAYER TURN: ", listaJogadores[jogadorAtual % len(listaJogadores)])
If that's not what you need for your game, let me know.
Original answer: Is the game ending or is it crashing? When I run the game, it always crashes with:
File "C:\Users\me\Desktop\Untitled-1.py", line 56, in <module>
diceDrawns.append(diceDrawn)
AttributeError: 'int' object has no attribute 'append'
This is because after looping, you try to do diceDrawns.append(), but you've already replaced the diceDrawns list with an integer on line 87. I'm not sure if you meant to replace diceDrawn instead, but that's definitely the source of the problem.
An unrelated note: You can do += as a shorthand way to increment a variable by a certain amount, so you can replace a lot of instances of things like currentPlayer = currentPlayer + 1 with currentPlayer += 1, and the same can be done with any operator, so you could also do things like -= or *=

Menu-driven collection of non-negative integers

I'm attempting to create a menu-driven program where python will accept a collection of non-negative integers. It will calculate the mean and median and display the values on the screen. I want my first option to be "Add a number to the list/array", I want my second option to be "Display the mean", the third to be "Display the median", the fourth "Print the list/array to the screen", the fifth "Print the list/array in reverse order" and the last option "Quit". So far I have gotten:
def main():
myList = [ ]
addOne(myList)
choice = displayMenu()
while choice != '6':
if choice == '1':
addOne(myList)
elif choice == '2':
mean(myList)
elif choice == '3':
median(myList)
elif choice == '4':
print(myList)
elif choice == '5':
print(myList)
choice = displayMenu()
print ("\nThanks for playing!\n\n")
def displayMenu():
myChoice = '0'
while myChoice != '1' and myChoice != '2' \
and myChoice != '3' \
and myChoice != '4' and myChoice != '5':
print("""\n\nPlease choose
1. Add a number to the list/array
2. Display the mean
3. Display the median
4. Print the list/array to the screen
5. Print the list/array in reverse order
6. Quit
""")
myChoice = input("Enter option---> ")
if myChoice != '1' and myChoice != '2' and \
myChoice != '3' and myChoice != '4' and myChoice != '5':
print("Invalid option. Please select again.")
return myChoice
#This should make sure that the user puts in a correct input
def getNum():
num = -1
while num < 0:
num = int(input("\n\nEnter a non-negative integer: "))
if num < 0:
print("Invalid value. Please re-enter.")
return num
#This is to take care of number one on the list: Add number
def addOne(myList):
while True:
try:
num = (int(input("Give me a number:")))
num = int(num)
if num < 0:
raise exception
print("Thank you!")
break
except:
print("Invalid. Try again...")
myList.append(num)
#This should take care of the second on the list: Mean
def mean(myList):
myList = [ ]
listSum = sum(myList)
listLength = len(myList)
listMean = listSum / listLength
print("The mean is", listMean)
#This will take care of number three on the list: Median
def median(myList):
median = 0
sortedlist = sorted(myList)
lengthofthelist = len(sortedlist)
centerofthelist = lengthofthelist / 2
if len(sortedlist) % 2 ==0:
return sum(num[center - 1:center + 1]) / 2.0
else:
return num[center]
print("The mean is", centerofthelist)
#This will take care of the fourth thing on the list: Print the list (In order)
def sort(myList):
theList.sort(mylist)
print(myList)
#This will take care of the fifth thing on the list
def reversesort(myList):
theList.sort(reverse=True)
print(myList)
main()
After I run the program I can't get past creating the list.

Corrected code with minimum changes:
def main():
myList = []
choice = 1
while choice != 6:
if choice == 1:
option1(myList)
elif choice == 2:
option2(myList)
elif choice == 3:
option3(myList)
elif choice == 4:
option4(myList)
elif choice == 5:
option5(myList)
choice = displayMenu()
print ("\nThanks for playing!\n\n")
def displayMenu():
myChoice = 0
while myChoice not in [1, 2, 3, 4, 5]:
print("""\n\nPlease choose

""")
myChoice = int(input("Enter option---> "))
if myChoice not in [1, 2, 3, 4, 5]:
print("Invalid option. Please select again.")
return myChoice

def option2(myList):
print("The mean is ", sum(myList) / len(myList))
# Option 3: Display the median
def option3(myList):
sortedlist = sorted(myList)
if len(sortedlist) % 2:
median = myList[int(len(sortedlist) / 2)]
else:

median = sum(myList[center-1:center+1]) / 2
print("The median is", median)
# Option 4: Print the list/array
def option4(myList):
print(sorted(myList))
# Option 5: Print the list/array in reverse order
def option5(myList):
print(sorted(myList, reverse=True))
main()
How I would do this:
The first part of the following code are a set of constants to customize the style of the menu. Then a set of functions representing each option are defined. The following 3 functions should not be modified, they generate the menu, display it and close the application. Then the main section starts, where you need to pass every option as an argument to setOptions(). The rest should not be modified either as it is the main loop.
# Menu formatting constants
MENU_HEADER = "Please choose an option:"
MENU_FORMAT = " * {:2}. {}"
MENU_QUIT_S = "Quit"
MENU_ASK_IN = "Enter option: "
MENU_INT_ER = "ERROR: Invalid integer. Please select again."
MENU_OPT_ER = "ERROR: Invalid option. Please select again."
END_MESSAGE = "Thanks for playing!"
# OPTIONS FUNCTIONS START HERE
def addElement(l):
""" Add a number to the list/array. """
n = -1
while n < 0:
try:
n = int(input("Enter a non-negative integer: "))
except ValueError:
print("It needs to be an integer.")
n = -1
else:
if n < 0:
print("It needs to be a non-negative integer.")
l.append(n)
def mean(l):
""" Calculate the mean. """
print("Mean: {:7.2}".format(sum(l) / len(l)))
def median(l):
""" Calculate the median. """
l = sorted(l)
p = int(len(l) / 2)
print("Median: {:7.2}".format(l[p] if len(l)%2 else sum(l[p-1:p+1])/2))
def oprint(l):
""" Print the list/array. """
print(sorted(l))
def rprint(l):
""" Print the list/array in reverse order. """
print(sorted(l, reverse=True))
# OPTIONS FUNCTIONS END HERE
def onQuit(l):
""" Function to execute when quitting the application. """
global quit
quit = True
print(END_MESSAGE)
def setOptions(*args):
""" Generates the menu and the options list. """
# Menu header and quit option (option 0)
menu = [MENU_HEADER]
options = [onQuit]
# Passed arguments represent texts and functions of additional options
for i, f in enumerate(args, start=1):
menu.append(MENU_FORMAT.format(i, f.__doc__.strip()))
options.append(f)
# We print the option 0 the last one
menu.append(MENU_FORMAT.format(0, MENU_QUIT_S))
# Returning both the menu and the options lists
return tuple(menu), tuple(options)
def displayMenu(menu):
""" Display the menu and get an option that is an int. """
while True:
for line in menu:
print(line)
try:
choice = int(input(MENU_ASK_IN))
except ValueError:
print(MENU_INT_ER)
else:
return choice
if __name__ == '__main__':
# Pass the option functions to the setOptions function as arguments
menu, options = setOptions(

# Initiate the needed variables and start the loop
l = []

while not quit:
c = displayMenu(menu)
try:

There is an indentation error inside your function addOne.
myList.append(num) is inside the while loop, and just before that you have a break, so the number is never appended to the list because we have left the loop already.

Issue setting matplot points color and shape

Whenever I run the display_data function (when there is data to be run after successfully answering at least one calculation_game question) I get an error that says:
"ValueError: to_rgba: Invalid rgba arg "o"
to_rgb: Invalid rgb arg "o"
could not convert string to float: 'o'"
When I run the code without the "o" to define the shape of the points it works fine and displays blue points. Only thing is that I want to be able to define shapes such as "o" and "v" because the plot will be showing data from multiple list when it is done. Any ideas?
NOTE:
There are missing functions below. I removed them here because they are not needed for the question.

Why is this python "War" card game freezing after only a few games?

Basically, I'm trying to test how the order of the cards in a players hand affects how often they win, but I run the program and the score will sometimes get stuck at player one alternating between 27 & 26 cards in hand, while player two alternates between 25 & 26 cards in hand and it just sticks like that.

Thanks to #Engineero for your comment:
There are possible infinite games in War, provided you do not switch the order in which player's cards are added to the bottom of the winning player's deck (i.e. always opponent's card first, then yours or vice versa). See this MathOverflow discussion. Basically for some deals, the game never ends. You could add occasional switching to the order that cards are returned to the bottom of the deck to make it finite. – Engineero
That led me to this solution:
Basically, I randomized which card was put in the pile first as such:
if random.randint(1,2) == 1:
war.append(player2[0])
war.append(player1[0])
else:
war.append(player1[0])
war.append(player2[0])
And this fixed the problem perfectly.

List object occurrence checker python

I was working on a small project, and I've run across a little error in my programming. It's a basic battleship game, and so far I have two "ships" set, and I have the game to end when both on either my side or the enemy side is hit.
def enemy_board():
global enemy_grid
enemy_grid = []
for i in range (0,10):
enemy_grid.append(["="] * 10)
def random_row_one(enemy_grid):
return randint(0, len(enemy_grid) - 1)
def random_col_one(enemy_grid):
return randint(0, len(enemy_grid) - 1)
def random_row_two(enemy_grid):
return randint(0, len(enemy_grid) - 1)
def random_col_two(enemy_grid):
return randint(0, len(enemy_grid) - 1)
global x_one
x_one = random_row_one(enemy_grid)
global y_one
y_one = random_col_one(enemy_grid)
global x_two

global y_two
y_two = random_col_two(enemy_grid)
print(x_one)
print(y_one)

So that's the basis of my list, but later on in the code is where it's giving me a little trouble.

I'm using python 3 if that makes any difference. So it's that if the player hits the correct spot on the grid, then it'll show as "H" and not as "=" or "O". So I was just wondering about if I could count those "H"'s to use to end the IF loop.

You haven't really explained the problem, and so much of the code is missing that it's very hard to tell you what's wrong, I'm going to guess at it though.
My guess is that you create an '=' grid to represent a player's board, and then if their ship is 'hit' you replace the '=' in that position with an 'H'.
The structure you create (enemy_grid) seems to look something like:
[[====]
[====]
[====]
[....]]
in which case your test, enemy_grid.count("H") doesn't make sense as enemy_grid is a list that contains other lists (so the count of Hs will always be 0 - they're deeper down in the 2nd layer of lists).
You probably want a test more along the lines of:
[cell for row in enemy_grid for cell in row].count('H')
