使用sleep（），它以秒为单位获取参数。

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)

您需要从时间导入它，因为我上面.
或者，如果你在while循环的末尾只有一个sleep（）函数而不是几个sleep（）函数，那么它会更有效，更易维护。下面是一个更好的例子，谢谢Max的建议。

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)

您可以在代码中任何需要等待的地方引入睡眠。

import time

time.sleep(5) # sleep for 5 seconds
