Python3.8 异常AttributeError module ‘time’ has no attribute ‘clock’

原由:time.clock() 自从python3.3之后就被废除
出现异常:
在pycharm中加Python3.8环境,调用time.clock出异常:AttributeError module 'time' has no attribute 'clock'
经过度娘,其原因:
Python3.8不再支持time.clock,但在调用时依然包含该方法;
有效处理:
用time.perf_counter()替换
- import time
- tis1 =time.perf_counter()
- print("等待5秒......")
- time.sleep(5)
- tis2=time.perf_counter()
- print(tis2-tis1)
- 等待5秒......
