eliminates the need to create a complete list, which saves a lot of space. In Python, this side loop computes the mechanism, called the Generator (Generator).To create a generator, there are a number of ways, the first method is simple, as long as a list-generated [] is cha

, "indicators" are used as the output, and the weight of each rule is calculated using the mechanical learning method. If you can organize a powerful neural network, you can directly use the entire number as the input. But someone has certainly studied this problem, right? So before doing this job-first look for the paper! Regular Expression filtering is supported.For example, (\ d) \ 1 {2,} indicates that the same

Python iterator toolkit [recommended], python generator Toolkit Original article: https://git.io/pytips 0x01 introduces the concept of iterator, that is, objects defining the _ iter _ () and _ next _ () methods, you can also use yield to simplify the definition of "iteratable objects". In some functional programming languages (see functional programming in

Generator #生成器 Can iterate Can only be read once Generate data in real time, not all in memory With a list build, we can create a list directly. However, with memory limitations, the list capacity is certainly limited. Also, creating a list of 1 million elements takes up a lot of storage space, and if we just need to access the first few elements, the vast majority of the space behind it is wasted. If a list element can be inferr

In Java we can use the Java.util.Random class to produce a random number generator. It has two forms of constructors, each of which is random () and random (long Seed). Random () uses the current time, System.currenttimemillis ()

resulting results to approximate the simulation of complete random numbers, this random number is called pseudo random number. Pseudorandom numbers are selected from a limited set of numbers with the same probability. The chosen number
