1. Data structureA data structure is a collection of information that is organized in some way. The most basic data structure is the sequence .2. Sequence The types commonly used in a sequence are the following six classes: list, tuple, string, Unicode string, buffer object, Xrange object.3. List(1) What is a list? Lists are made up of numbers, strings, etc., and can be modified arbitrarily.A = [' samp ', ' eggs ', 520, 100, 34] (2) Operation of t

With the increasing number of overclocking players, the asynchronous memory technology has also begun to flourish. However, the technological development has also brought about more confusion. Even the "prawns" cannot fully figure out the current asynchronous memory technology. It is precisely for this reason that memory asynchronous technology is necessary to solve the problem. If you are interested, you may go on to understand what the memory asynchronous technology is like!
