有沒有辦法讓 python 程序等待幾秒鍾？ 我正在制作無限數量的打印機，但速度太快，無法讀取

Question

我不知道如何讓我的程序等待幾秒鍾，這樣我才能真正閱讀它 python 中是否有等待函數或是否有此類模塊？ 我沒有辦法在窗口中運行它，因為我在學校的 chromebook 上。

My Code:


from random import randint

while True:
    a = randint(0,999999)
    b = randint(0,999999)
    c = randint(0,999999)
    
    if (a <= b) or (a <= c):
        print("variable 'a' has been printed")
        print(a)
        
    elif (b <= a) or (b <= c):
        print("variable 'c' has been printed")
        print(b)
        
    elif (c <= a) or (c <= b):
        print("variable 'c' has been printed")
        print(c)
    
    elif (a == b):
        print("Combo of 'a' + 'b'")
        print(a + b)
        
    elif (a == c):
        print("Combo of 'a' + 'c'")
        print(a + c)
    
    elif (b == c):
        print("Combo of 'b' + 'c'")
        print(b + c)


How to make it wait?

Answer 1

使用 sleep()，它會在幾秒鍾內獲取參數。

from random import randint
from time import sleep
while True:
    a = randint(0,999999)
    b = randint(0,999999)
    c = randint(0,999999)

    
    if (a <= b) or (a <= c):
        print("variable 'a' has been printed")
        print(a)
        sleep(1)
        
    elif (b <= a) or (b <= c):
        print("variable 'c' has been printed")
        print(b)
        sleep(1)
        
    elif (c <= a) or (c <= b):
        print("variable 'c' has been printed")
        print(c)
        sleep(1)
    
    elif (a == b):
        print("Combo of 'a' + 'b'")
        print(a + b)
        sleep(1)
        
    elif (a == c):
        print("Combo of 'a' + 'c'")
        print(a + c)
        sleep(1)
    
    elif (b == c):
        print("Combo of 'b' + 'c'")
        print(b + c)
        sleep(1)

你需要像我上面那樣從時間導入它。

或者，如果在 while 循環的末尾只有一個 sleep() 而不是多個 sleep() 函數，它將更加高效和可維護。 下面是上面代碼的一個更好的例子。 感謝 Max 的建議。

from random import randint
from time import sleep
while True:
    a = randint(0,999999)
    b = randint(0,999999)
    c = randint(0,999999)


    if (a <= b) or (a <= c):
        print("variable 'a' has been printed")
        print(a)
    
    elif (b <= a) or (b <= c):
        print("variable 'c' has been printed")
        print(b)
    
    elif (c <= a) or (c <= b):
        print("variable 'c' has been printed")
        print(c)

    elif (a == b):
        print("Combo of 'a' + 'b'")
        print(a + b)
    
    elif (a == c):
        print("Combo of 'a' + 'c'")
        print(a + c)

    elif (b == c):
        print("Combo of 'b' + 'c'")
        print(b + c)

    sleep(1)

您可以在需要等待的任何地方在代碼中引入睡眠。

import time

time.sleep(5) # sleep for 5 seconds
