Question

我运行代码并且它工作得很好，但它只记录最后一个反应时间而不是所有反应时间。我似乎无法找到什么错误。我建立了另一个类似于此的程序，我检查了两个并进行了比较，但仍然无法正常工作

#Builds PyGame Screen
pygame.init()

x = float(2)

#For Loop
for turn in range(3):

    screen.fill((255, 255, 255))

    pygame.display.flip()

#Delay Before The Rest Of The Program Is Runned
    time.sleep(x)

#Draws A Black Circle And Starts Runing The Reaction Program

Answer 1

每当您需要w附加到您的文件时，

a会覆盖您的内容。

`open("z output.txt", "a")`

您还应该使用以打开文件，因为它会自动关闭它们：

`with open("z output.txt", "w") as reactiontimes:`

只写最后一次反应时间
