About crawlers, began to think that only crawling web data, and then know that the app can crawl. As a result, the use of idle time in schools took two weeks to achieve data capture and simple data analysis.Goal, crawl Super Curriculum XX University (in fact, it is our university ...) ) Students 20,000 post information. Ideas are as follows:　　　　STEP1: Find the entrance for our reptile　　　　The app requests the data, also through the network protocol, so

There was not much understanding of Python before, just a simple knowledge of a computer language. As a computer small white, feel computer language is very mysterious, to Python also have a certain sense of fear. Isn't Python hard to learn? What practical problems can python solve? Does Python have a wide range of applications? And so on a series of questions also made me curious about python. When you really start to learn, it's interesting to know that Python can be used to solve many practic

If I can learn Java again, I will be in accordance with the requirements of the teacher to do every link, to Java learning pour my cavity blood!Finally to Lou teacher and seniors learn elder s

Starting from today, we will step by step implement what we want to achieve in demand analysis. First, we will achieve dynamic display of the date and time at the top of the curriculum. The date is automatically updated every day, and the time is dynamically changed in seconds. There are two classes for processing java time and Date: Date () and Calendar (). Since the Date and time are processed from java, it is recommended that you use Calendar (

in a bit of classroom atmosphere, the teacher is not clear whether the students are thinking about the problem. I think to solve this kind of problem to let the students say their own ideas, bold to speak, so as to achieve the purpose of the discussion. Students generally shy, embarrassed in front of the class to speak aloud their ideas. You can implement the reward system, such as the discussion of the positive performance of the students plus how many points, give full play to the students in

The Python course has been around for two weeks, telling the truth that there was some hesitation in choosing the course, and that there was no understanding of the course, only that it was learning about programming. As a liberal arts student, the beginning is very uncertain. But after taking this course, some people say that Python teacher is very good, so later after the class, found that Xiao teacher really speak very well, not imagined boring boring, and re-ignite the confidence of learning

In general, a series of feature templates are given, as shown in the following three feature templates: (a) Cn (n= -2,-1,0,1,2) (b) cncn+1 (n=-2,-1,0,1) (c) C-1C1 For example, fo
