AttributeError: module 'time' has no attribute 'clock'】

这个报错是因为 Python 3.3 版本开始,`time.clock()` 方法已经被废弃。你可以使用 `time.perf_counter()` 或 `time.process_time()` 替代它,具体取决于你要测量的时间类型。以下是两个示例:
使用 `time.perf_counter()` 测量一个函数的执行时间:
```python
import time
start_time = time.perf_counter()
# 执行你的代码或函数
end_time = time.perf_counter()
execution_time = end_time - start_time
print(f"执行时间: {execution_time} 秒")
```
使用 `time.process_time()` 测量一个函数的 CPU 时间:
```python
import time
start_time = time.process_time()
# 执行你的代码或函数
end_time = time.process_time()
execution_time = end_time - start_time
print(f"CPU 时间: {execution_time} 秒")
```
请注意,`time.clock()` 在 Python 3.8 中已被完全移除,所以建议使用新的替代方法。

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")
```
AttributeError: module 'time' has no attribute 'clock
AttributeError: module 'time' has no attribute 'clock'错误是因为Python 3.8之后的版本不再支持time.clock()方法。解决这个问题的方法是将time.clock()替换为time.perf_counter()。这两个方法的作用都是一样的。所以你可以将代码中的time.clock()替换为time.perf_counter()来解决这个错误。
以下是替换后的代码示例:
import time
scale = 50
print("执行开始".center(scale//2, '-'))
t = time.perf_counter()
for i in range(scale-1):
a = '*' * i
b = '.' * (scale - i)
c = (i/scale) * 100
t -= time.perf_counter()
print("\r{:^3.0f}%[{}->{}]{:.2f}s".format(c, a, b, -t), end='')
time.sleep(0.05)
print("\n" "执行结束".center(scale//2, '-'))
