frequency-controller的Python项目详细描述
频率控制器
频率限制。从torequests复制的代码段。在
简介
- There are many implementations for frequency-control, the generator way is better than using a Queue
- Queue instances use more memory
- Queue initial process is slower than create a generator
- Python3.8+ required the lock protection for async-generators.
- https://bugs.python.org/issue38559
- But 3.6 / 3.7 don't have this feature
- Using timeit.default_timer for a better accuracy but little performance lost.
- Frequency.TIMER = timeit.default_timer
安装
pip install -U frequency_controller
