我想做的是
所以我基本上想做的是，每次一辆车通过终点线时，它都会说哪辆车有一辆，但我要做的是每次第一辆车赢了，第二辆车通过了终点线时我想说的是，哪辆车在上获得了第二名和第三名，以此类推

所以，你得到的代码是有效的，唯一的问题是当汽车与终点线相交时，你只是在屏幕上闪电式地显示文本
因此，在每一帧的屏幕上都有一个字符串，当一辆车过线时，将字符串更改为该车的
#put these outside the game loop
finish_text = ""
font2 = pygame.font.SysFont("Papyrus", 45)
players_finished = 0
placings = ["1st", "2nd", "3rd", "4th"]
while running: #game loop
...
# Did anyone cross the line?
if (finish_line_rect.collidepoint(playerX, playerY)):
if finish_text[:9] != "Player 1": #so it doesnt do this every frame the car is intersecting
finish_text = "Player 1 is " + placings[players_finished]
players_finished += 1
print("Player (one) has crossed into finish line!")
elif (finish_line_rect.collidepoint(playerX_two , playerY_two)):
if finish_text[:9] != "Player 2":
print("Player one has crossed into finish line first other car lost!")
finish_text = "Player 2 is " + placings[players_finished]
players_finished += 1
elif (finish_line_rect.collidepoint(playerX , playerY)):
if finish_text[:9] != "Player 3":
print("Player two has crossed into finish line first other car lost!")
finish_text = "Player 3 is " + placings[players_finished]
players_finished += 1
elif (finish_line_rect.collidepoint(playerX_two, playerY_two)):
if finish_text[:9] != "Player 4":
print("Player two has crossed into finish line first other car lost!")
finish_text = "Player 4 is " + placings[players_finished]
players_finished += 1
if finish_text != "": #test to see if there is anything to put on screen
text2 = font2.render(finish_text, 5, (255, 99, 7))
screen.blit(text2, (135 - (text2.get_width() / 5), 95))

注意。还没有测试过
我从未使用过pygame，所以不知道是否有内置函数。然而，你可以很容易地做一个计数器。
#this is all in your while loop
if playerY<50 or playerY_two<50 or playerY_three<50 or playerY_four<50:
count+=1
if count == 1:
if playerY<50:
print('playerY first place')
playerY=10000
if playerY_two<50:
print('playerY_two first place')
playerY_two=100000
if playerY_three<50:
print('playerY_three first place')
playerY_three=100000
if playerY_four<50:
print('playerY_four first place')
playerY_four=1000000
if count == 2:
if playerY<50:
print('playerY second place')
playerY=10000
if playerY_two<50:
print('playerY_two seoncd place')
playerY_two=100000
if playerY_three<50:
print('playerY_three second place')
playerY_three=100000
if playerY_four<50:
print('playerY_four second place')

print('playerY third place')

print('playerY_two third place')
playerY_two=100000
if playerY_three<50:
print('playerY_three third place')
playerY_three=100000
if playerY_four<50:
print('playerY_four third place')
playerY_four=1000000
if count == 4:
if playerY<50:
print('playerY 4th place')
playerY=10000
if playerY_two<50:
print('playerY_two 4th place')
playerY_two=100000
if playerY_three<50:
print('playerY_three 4th place')

print('playerY_four 4th place')

您可以创建一个类/函数，将上面的全部内容写在4行到5行中，但总体思路是您希望打印出谁越过了终点线，但您只希望打印出一次。
