how to make a pygame friction simulation [duplicate]

I am trying to make a golf game, but I am unable to get a friction simulation to work. the golf ball x and y moves by two variables speedX, speedY speedX and speedY decrease by a variable friction which increases. But this doesn't seem to work

heres the code

import pygame

pygame.init()

class Ball:
    def __init__(self, win):
        self.win = win
        self.color = (255, 255, 255)
        self.width = self.win.get_width()/2
        self.height = self.win.get_height()/2

        self.speedX = 70
        self.speedY = 70
        self.friction = 3
        self.clicked = False

        self.x = self.width / 2
        self.y = self.height / 2

        self.base = pygame.Rect(0, 0, 20, 20)
        self.base.center = (self.x, self.y)

    def render(self):
        self.base.center = (self.x, self.y)
        pygame.draw.ellipse(self.win, self.color, self.base)

    def __str__(self):
        return f"speedX: {self.speedX}, speedY: {self.speedY}, friction: {self.friction}"

    def move(self):
        if self.friction <= 0 or self.speedX <= 0 or self.speedY <= 0:
            print("ASD")
            self.clicked = False
            self.speedX = 70
            self.speedY = 70
            self.friction = 5

        if self.clicked:
            print(self.__str__())
            if self.base.left <= 0:
                self.speedX *= -1

            if self.base.right >= self.width:
                self.speedX *= -1

            if self.base.top <= 0:
                self.speedY *= -1

            if self.base.bottom >= self.height:
                self.speedY *= -1

            if self.speedX > 0:
                self.speedX -= self.friction
            if self.speedX < 0:
                self.speedX += self.friction

            if self.speedY > 0:
                self.speedY -= self.friction
            if self.speedY < 0:
                self.speedY += self.friction

            self.friction -= 0.1

            self.x += self.speedX
            self.y += self.speedY


class Game:
    def __init__(self):
        self.width = 600
        self.height = 600
        self.fps = 60
        self.running = True
        self.color = (0, 0, 0)

        self.win = pygame.display.set_mode((self.width, self.height))
        self.clock = pygame.time.Clock()
        self.ball = Ball(self.win)

    def run(self):
        while self.running:
            pygame.display.update()
            self.win.fill(self.color)
            self.clock.tick(self.fps)

            self.ball.render()
            self.ball.move()

            pos = pygame.mouse.get_pos()

            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    self.running = False

                if event.type == pygame.MOUSEBUTTONDOWN and self.ball.base.collidepoint(pos):
                    self.ball.clicked = True

        pygame.quit()

if __name__ == '__main__':
    Game().run()

How to show number of registered users in Laravel based on usertype?

i'm trying to display data from the database in the admin dashboard i used this: <?php use Illuminate\Support\Facades\DB; $users = DB::table('users')->count(); echo $users; ?> and i have successfully get the correct data from the database but what if i want to display a specific data for example in this user table there is "usertype" that specify if the user is normal user or admin i want to user the same code above but to display a specific usertype i tried this: <?php use Illuminate\Support\Facades\DB; $users = DB::table('users')->count()->WHERE usertype =admin; echo $users; ?> but it didn't work, what am i doing wrong? source https://stackoverflow.com/questions/68199726/how-to-show-number-of-registered-users-in-laravel-based-on-usertype

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
