Pygame colliderect() function returning 0 (zeros) and 1 (ones) instead of True and False? [duplicate]

This question already has answers here:
How do I detect collision in pygame?
(5 answers)
Closed last year.
colliderect() function won't return True and False; instead, it is returning 0 and 1. When I use the function type it says int instead of bool. If I code using 0 and 1 instead of the boolean value the code works, but why is it happening? Pygame documentation doesn't mention anything about it.
def collisions():
tileHitsList = []
for rect in tileList:
print(testcube.colliderect(rect)) #it weirdly prints 0 and 1 instead of False and True
#tileList is a list which contains the rects of the tiles being rendering on the display
#testcube is a rect that hits the tiles
if testcube.colliderect(rect) == True:
tileHitsList.append(rect)
return tileHitsList

It's pretty normal if the pygame documentation didn't say anything about it, as 1 and 0 are very commonly used to replace True and False.
You can just do
if testcube.colliderect(rect):
# Your code
without the ==.
Here is a documentation on the matter: https://docs.python.org/3/reference/datamodel.html#index-10

I have to make a game where n people play hangman and the game keeps their results and if they win the round, then they go on until there is only one player left(that player wins) or none left(nobody wins). My hangman code is ready, so I do not need anything concerning the hangman function. However, I need some help to make a function that does the following:
1)Asks how many players will play
2)Asks their names and stores them
3)Plays the first round and if hangman()==True (meaning the player won) for a player, then this player goes on to the next round, otherwise not
4)If somebody wins, then we have a winner and the game ends
I have already made the part that the game asks the number of player, asks their names and makes them play. My hangman() function returns either True or False. However, it seems that I have a problem. Every time a player plays the game, the hangman() function runs twice. I don't know why this happens. I would like some help fixing that and also to write the part where each round is played.
def game():
players_dict={}
results=[]
num_of_players=int(input('How many players will play? '))
for i in range(1,num_of_players+1):
a=input('Give the name of Player {}: '.format(i))
players_dict['Player {}'.format(i)]=a
for i in range(1,num_of_players+1):
print(players_dict['Player {}'.format(i)])
hangman()
if hangman()==False:
results+=False
else:
results+=True

All you need to do is get rid of the first hangman() call:
...
for i in range(1, num_of_players + 1):
print(players_dict['Player {}'.format(i)]
if hangman() is False:
results += False
else:
results += True
If you need to keep hold of the value returned, assign it to a variable beforehand:
...
r = hangman()
if r is False:
results += False
else:
results += True
Furthermore, you can shorten this code simply by writing the following (assuming you don’t keep the result):
results += hangman()

+= and -= expressions in Python (?) [duplicate]

This question already has answers here:
What exactly does += do?
(17 answers)
Why does += behave unexpectedly on lists?
(9 answers)
Closed 5 years ago.
I am trying to follow the example in this post, and it was going smoothly until I ran into the lines of code with -= and += calls.
I believe this might be some sort of misprint in expressions that are supposed to update the object on the RHS of = according to some condition.
Unfortunately, interpreting this expression is key in getting what the code is doing, and guessing defeats the purpose.
Do these fragments of code or operators make any sense?
What was intended by the author?

x -= y, x += y and so forth are a shorthand way of writing x = x - y and x = x + y respectively.

These are shorthands.
a -= b
means
a = a -b
The meaning of += should be fathomable now.
But, it seems that you might have gotten some Exception. In that case, feel free to post it, and your code.

Window opening procedure [duplicate]

Why does pygame.display.update() not work if an input is directly followed after it?

Closed 1 year ago.
I have an instruction I need to do:
a procedure taking into parameter two integers 'l' and 'h' (length and width)assumed positive and a filename with the corresponding extension of an image. it will create a window of 'l' length and 'h' width and will affect a random value (R,G,B form) to each of it's pixels, finally it will save this image in the current directory under the name passed into parameter
Here's my (messy) code:
def surf (l, h, imagech):
pygame.init()
ecran = pygame.display.set_mode("RGB",(l, h))
fond = pygame.image.load("MPchiffre.bmp").convert()
surface.blit(fond, (0,0))
pygame.display.flip()
continue = 1
while continue:
continue = int(input())
pixels = getPixelArray('MPchiffre.bmp')
nu.random.randint(0, 255)
pygame.image.save(surface, "imagech.bmp")
my main issue is syntax basics and basic understanding of python, I don't have time to review all of it, if someone could tell me what's wrong with this code it would be nice.

def update(self):
# Get the current mouse position. This returns the position
# as a list of two numbers
pos = pygame.mouse.get_pos()
# Fetch the x and y out of the list,
# just like we'd fetch letters out of a string.
# Set the player object to the mouse location
self.circ.x=pos[0]
self.circ.y=pos[1]
Initialize Pygame
right where the self.circ.x=pos[0] is there seems to be a unident/indentation error, i am new to python and was wondering what was wrong?

You have a whitespace before pos variable delete it.
def update(self):
# Get the current mouse position. This returns the position
# as a list of two numbers
pos = pygame.mouse.get_pos()
# Fetch the x and y out of the list,
# just like we'd fetch letters out of a string.
# Set the player object to the mouse location
self.circ.x=pos[0]
self.circ.y=pos[1]

Pos is located one far too right.

The line
pos = pygame.mouse.get_pos()
has an extra space. To see that clearly, removing the comments helps.
pos = pygame.mouse.get_pos()
self.circ.x=pos[0]
self.circ.y=pos[1]
