What do people use Python for?
Do website backend: There are a large number of mature frameworks, such as django, flask, bottle, tornado
Writing web crawlers: Python is very simple to write crawlers, and the library is very sound
Scientific Computing: Participate in the mathematical modeling contest, which can completely replace R language and MATLAB
Data Mining: Machine Learning: There are many machine learning packages for Python
Data Science: Recently Spark and Hadoop have opened Python interfaces, so it is very simple to use Python to do mapreduce for big data.
Automated operation and maintenance: scripts for system deployment and daily maintenance
See how powerful Python is. I have used Python to process some of the network data grabbing needed for work now. For a novice, what should be paid attention to when learning Python, and which are the key points. If you learn Python by yourself and find a development job, what should be the key points?
Let's analyze it in detail below.
Learn Python, what exactly do you learn?
1) If you want to learn Python to understand the programming language and make some practical gadgets to improve efficiency, the main content of learning should be Python network access (urllib, urllib2, requests), crawler-related libraries, regular expressions, BeautifulSoup, XPath, Excel, database MySQLdb module, etc., understand html web pages.
This knowledge is skillfully applied, and data is captured from the Internet and then analyzed and processed. There is no problem at all.
2) If you want to learn Python language and find a development job, then look at the requirements of the company's position.
1. The Python language is very easy to use as a tool for improving efficiency at work.
2. If you don't have a programming language foundation and want to engage in development after learning Python, the requirements are high. The focus should be on web learning, framework (Flask, Django) learning, html, js are the basics. At the same time, we must lay a good foundation for Linux.
