圆周率pi的运输，这报错是因为我电脑缺少time的库吗？

Question

pi.py

from random import random
from math import sqrt
from time import clock
DARTS = 1200
hits = 0
clock()
for i in range(1,DARTS):
x, y = random(), random()
dist = sqrt(x2 + y2)
if dist <= 1.0:
hits = hits + 1
pi = 4 * (hits/DARTS)
print("Pi的值是 %s" % pi)
print("程序运行时间是 %-5.5

ss" % clock())

Answer 1

3.3版本之后应该已经移出了，可使用perf_counter()或者process_time()代替。
