Question

我正在使用＆＃34;随机＆＃34;来制作代码来更改变量每次迭代中的函数，不断检查变量是否等于特定的预定义值。如果相等，代码将停止，记录达到该值所需的时间。代码工作正常并且正如预期的那样，直到我介绍了我的计时方法，使用time.time（）。

为什么我收到错误声明我的语法在＆＃34; start = time.time（）＆＃34;无效（第5行）？

我在其他代码中测试了相同的设置，它完美无缺。我该如何解决这个问题？

提前致谢。

import random
import time
VARIABLE = int(random.randint(1, 16))
function = int(0)
start = time.time()
while True:
  function = int(random.randint(1,16))
  if not VARIABLE == int("0"):
    if function == int("1"):
      VARIABLE = int(VARIABLE) + int(random.randint(1,1000))
    if function == int("2"):
      VARIABLE = int(VARIABLE) - int(random.randint(1,1000))
    if function == int("3"):
      VARIABLE = int(VARIABLE) * int(random.randint(1,1000))
    if function == int("4"):
      VARIABLE = int(VARIABLE) / int(random.randint(1,1000))
    if function == int("5"):
      VARIABLE = int(random.randint(1,1000)) / int(VARIABLE)
    if function == int("6"):
      VARIABLE = int(VARIABLE) + int(random.randint(1,1000))
    if function == int("7"):
      VARIABLE = int(random.randint(1,1000)) - int(VARIABLE)
    if function == int("8"):
      VARIABLE = int(VARIABLE) ^ int(random.randint(1,1000))
    if function == int("9"):
      VARIABLE = int(random.randint(1,1000)) ^ int(VARIABLE)
    if function == int("10"):
      VARIABLE = (int(VARIABLE) * int(random.randint(1,1000)))^2
    if function == int("11"):
      VARIABLE = (int(VARIABLE) + int(random.randint(1,1000)))^2
    if function == int("12"):
      VARIABLE = (int(VARIABLE) - int(random.randint(1,1000)))^2
    if function == int("13"):
      VARIABLE = (int(VARIABLE) / int(random.randint(1,1000)))^2
    if function == int("14"):
      VARIABLE = (int(random.randint(1,1000))/int(VARIABLE))^2
    if function == int("15"):
      VARIABLE = (int(random.randint(1,1000)) - int(VARIABLE))^2
    if function == int("16"):
      VARIABLE = (int(VARIABLE) ^ int(random.randint(1,1000)))^2
    if function == int("16"):
      VARIABLE = (int(random.randint(1,1000))^int(VARIABLE))^2
  print int(VARIABLE)
  time.sleep(.75)
  if VARIABLE == int("42"):
    end = time.time()
    print("Task completed.")
    break
print("This time, we completed the task in "+(end-start)+ "seconds.")

虽然代码的time.time()部分适用于我，但在line 24上，您无法使用^来表示指数。在python中，您使用**。正如Nick在下面指出的，^是python中的按位exclusive or operator。

将变量定义为time.time（）
