AttributeError: module 'time' has no attribute 'clock'
时间: 2023-09-23 18:11:35 浏览: 20
在Python 3.8及以上版本中,`time.clock()`方法已被废弃,因此出现了`AttributeError: module 'time' has no attribute 'clock'`的错误。如果您的Python版本是3.8或更高版本,建议使用`time.perf_counter()`或`time.process_time()`方法来代替`time.clock()`。
例如,如果您想要计算程序运行的时间,可以使用以下代码:
```python
import time
start_time = time.perf_counter()
# 这里是您的程序代码
end_time = time.perf_counter()
print(f"程序运行时间为:{end_time - start_time:.6f}秒")
```
这里使用了`time.perf_counter()`方法来计算程序的运行时间。如果您需要计算CPU时间,则可以使用`time.process_time()`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, '-'))
