1. starting Python from IdieIdle is a python shell,shell meaning "shell", which is basically a way of interacting with the program by entering it. Windows like the cmd window, like the Black Command window of Linux, are all shells and can be used to give commands to the operating system. Similarly, you can use the idle shell to interact with the Pytho. >>> This prompt means: Python is ready, waiting for the Python command to be entered;baishuchaodemacbook-pro:~ xcn$ Python3.5python 3.5.2rc1 (V3.

Download the small turtle's algorithm and data structure video from the Internet, and intend to finish the series with the video. To achieve a preliminary understanding of the algorithm What is an algorithm? An algorithm is a description of the solution steps for a particular problem, represented as a finite sequence of instructions in the computer, and each of the bars represents one or more operations. (In short, the algorithm is the skill and the way to do all kinds of things)Re

Originally always used GitHub, from above to find some open source projects and source code. Because the laboratory does some small projects, but it is not convenient to open, but the GitHub built on the project is privately charged. Later I heard of git.oschina.com. As long as it is registered, each user can establish 1000 private items. Here's a way to share your own use of tortoisegit (turtle git) to manipulate Oschina. PS: The command line party d
