The last option that you’ll try here for timing your code is line_profiler. cProfile can tell you which functions your code spends the most time in, but it won’t give you insights into which lines inside that function are the slowest. That’s where line_profiler can help you. Note:...

$ python -m pip install codetiming 1. 理解Python 中的类 Class类是面向对象编程的主要构建块。类本质上是一个模板,可以使用它来创建对象。 在Python 中,当需要对需要跟踪特定状态的事物进行建模时,类非常有用。一般来说,类是属性的集合,称为属性,以及行为,称为方法。
time模块是Python专门用来处理时间的内建库。它自带了很多方法,可以将不同的时间类型进行相互转换,例如可以将时间戳类型转换为时间元组、时间元组转换为格式化时间、 格式化时间转换为时间戳... 时间处理是编程中一个比较常见的情况,比如转换时间类型:后端接口传参时通常是传递时间戳,前台拿到接口返回值中的时间戳通常...
