Replied to a topic by killva4624 问与答 为什么 π 会比 3.2 大?
测试了 Bard 的回答是对的
Q: Is π greater than 3.2?
A: No, pi is not greater than 3.2. Pi is an irrational number, which means that its decimal representation never ends or repeats. Its approximate value is 3.141592653589793. 3.2 is a rational number, which means that its decimal representation can be written as a fraction.

楼主三分法怎么实现的啊?我大概算了一下,230 步左右就可以求出来了啊?这样都满足不了要求么?
而且如果曲线没有其他性质的话,n 分法就是最优解了啊
貌似回复贴不支持代码块,缩进有点问题,但是应该也能看懂吧
@zhailw
```python
import time
import timeit as original_timeit


def timeit(times):
start_time = time.time()
yield from range(int(times))
used_time = time.time() - start_time
print('average used time:' + str(used_time / times))


rounds = int(1e6)

for _ in timeit(rounds):
"-".join(map(str, range(100)))

print('original_timeit: ', original_timeit.timeit('"-".join(map(str, range(100)))', number=rounds) / rounds)

print('done')
```
average used time:8.731926918029785e-06

original_timeit: 8.62705747198197e-06

done

@LeeReamond
有一个小问题啊,不知道楼主有没有想过用 for _ in timeit(1e6): 这种形式啊?不是更简单么?也比 with 多不了几个字符,但是感觉更优雅一点?
