attributeerror: module 'time' has no attribute 'clock'

这是一个 Python 编程错误。它表示在模块 "time" 中没有找到名为 "clock" 的属性/函数。可能是因为您在程序中使用了该属性/函数，但是它在运行时并不存在。

首先检查是否程序语法有误，例如拼写错误，大小写错误。
确认您正在使用的版本的time 模块是否存在这个方法.

可以使用‘help(time)’查看time模块中所有函数和属性,如果真的没有clock,那可能是过时的版本或者是其他原因导致的。

AttributeError: module time has no attribute clock

As an AI language model, I can tell you that the error message "AttributeError: module time has no attribute clock" means that the clock function that was previously used in Python 2 has been removed in Python 3. In Python 3, the time module has a new function called "perf_counter" that can be used instead of "clock" to measure the execution time of a program.

So, you can replace "time.clock()" with "time.perf_counter()" in your code to fix this error. Here is an example:

import time

start_time = time.perf_counter()

# your code here

end_time = time.perf_counter()

print(f"Execution time: {end_time - start_time:.5f} 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, '-'))
