Why do you want to learn python?

1) Daniel is using

2) easy to learn, compared to C + +

3) Python's powerful features

Learning Resources

　　I chose Google's Python Class QuickStart python (a two-day tutorial was recorded as a video, uploaded on YouTube). Books Use the Python Learning Handbook (4th edition) to consolidate knowledge and deepen understanding. There are a lot of simple tutorials on the web that can help, like Liaoche's Python tutorial.

Of course, the most important thing to learn a programming language is to knock on the code, I hope that I can stick to it, a lot of practice. It is worth mentioning that reading the Google Python style guide can be helpful in building good programming styles and habits.

Environment construction

　　1. Install Python:

Linux:

The Linux distribution I'm using is cent OS 6.5, and Python is already installed. Use VI or gedit to edit code on Linux
