module 'time' has no attribute 'clock' 解释

在Python 3中,time模块中的clock()函数已被废弃,因此在使用时会出现"module 'time' has no attribute 'clock'"的错误提示。如果想要获取当前时间,可以使用time模块中的time()函数。例如:
```
import time
start_time = time.time()
# 执行代码
end_time = time.time()
elapsed_time = end_time - start_time
print("程序执行时间:", elapsed_time)
```

module time has no attribute clock
在Python中,`time`模块确实没有`clock`属性。这是因为在Python 3.3版本后,`time.clock()`方法被废弃了。相反,你可以使用`time.perf_counter()`或`time.process_time()`来获取时间戳。
- `time.perf_counter()`方法返回一个高精度的性能计数器,用于测量短时间间隔。它包括了系统休眠时间。
- `time.process_time()`方法返回当前进程使用的CPU时间,不包括系统休眠时间。
以下是使用这些方法的示例:
```python
import time
start_time = time.perf_counter()
# 执行一些操作
end_time = time.perf_counter()
execution_time = end_time - start_time
print(f"执行时间: {execution_time}秒")
```

AttributeError: module time has no attribute clock
The error message "AttributeError: module time has no attribute clock" means that the "clock" attribute is not available in the "time" module.
The "clock" function was deprecated in Python 3.3 and removed in Python 3.8. Instead of using "time.clock()", you can use "time.perf_counter()" or "time.process_time()" depending on your use case.
Here's an example of using "time.perf_counter()" to measure the time taken for a piece of code to execute:
```
import time
start_time = time.perf_counter()
# Code to be timed
for i in range(1000000):
pass
end_time = time.perf_counter()
elapsed_time = end_time - start_time
print(f"Elapsed time: {elapsed_time:.6f} seconds")
```
