我正在创建一个名为“比特币点击器”的pygame项目，这是一个简单的游戏，你点击它，然后接收比特币。然后你可以到交易所“标签”交换比特币以获取金钱，然后你可以购买升级以便比特币闲置。
我没有让它工作的问题，但是，我编程足以知道if语句的连续“阶梯”效率不高。这是我的代码：
import decimal
import math
import pygame
pygame.init()
width = 900
height = 600
frame_rate = 60
black = (0, 0, 0)
white = (255, 255, 255)
red = (255, 0, 0)
green = (0, 255, 0)
blue = (0, 0, 255)
scene = 0
gameDisplay = pygame.display.set_mode((width, height))
pygame.display.set_caption("Bitcoin Clicker")

pentiumImg = pygame.image.load('KL Intel Pentium A80501.jpg')

click_value = 0.000001
pentium_price = .00001 * exchange_rate
passive_value = 0.0
bitcoin = 0.0
coin_x = (width / 2 - 100)
coin_y = (height / 2 - 100)
def coin(x, y):
gameDisplay.blit(bitcoinImg, (x, y))
def text_objects(string, font):
textSurface = font.render(string, True, white)
return textSurface, textSurface.get_rect()
def text(string, x, y, size):
largeText = pygame.font.Font('freesansbold.ttf', size)
TextSurf, TextRect = text_objects(string, largeText)
TextRect.center = (x, y)
gameDisplay.blit(TextSurf, TextRect)
def clicker():

pygame.quit()
quit()

if math.sqrt(x_squared + y_squared) < 100:
bitcoin += click_value

coin(coin_x, coin_y)
def store():
global cents
global scene

global passive_value
pentium_markup = 1.1
mouse_x = pygame.mouse.get_pos()[0]

有什么方法可以简化以下代码吗？特别是许多if语句。我从函数中删除了一些代码，以便于查看。 （每个功能都是一个单独的“标签”，根据用户输入呈现不同的屏幕）
