我收到了以下代码。我已经添加了time()来让我计算用户遇到问题和用户输入数据之间的延迟。
但结果时间并不总是正确的,我不确定原因。
from time import time
from random import randint
a = randint(0,1000)
b = randint(0,1000)
cor_answer = a+b
usr_answer = int(input("what is "+str(a)+"+"+str(b)+"? \n"))
start = time()
if usr_answer == cor_answer:
print("yes you are correct!")
else:
print("no you are wrong!")
end = time()
elapsed = end - start
print("That took you "+str(elapsed)+" seconds. \n")
这是从cmdline执行的结果:
~/math_quiz/math_quiz$ python3 math_quiz.py
what is 666+618?
1284
1284
1284
yes you are correct!
That took you 4.291534423828125e-05 seconds.
但是time()显然有效,因为如果我在IDLE中运行它,我会得到这个:
>>> start = time()
>>> time()-start
13.856008052825928
所以我不确定为什么cmdline的执行会给我带来不同的结果。

您的代码当前在用户输入答案后启动计时器
您需要在start = time()
usr_answer = int(input("what is "+str(a)+"+"+str(b)+"? \n"))
