Yesterday I saw a programmer "China doesn't talk about Python", and there are many people in China who don't python, and Python is very popular abroad. Think of the "Programmer's Tao", learn a language every year, think about yourself in the third grade, you can learn your own third door computer language - Phhon downloads ActivePython2.4 from the Internet, very installation Convenient, and inside the help documentation of ActivePython24.chm, very detailed, can be used to let you begin python. However, the information I learned today is the PDF provided by the << Dive Into Python >> (Mark, Pilgrim) programmer. Although it is an English version, it is very easy to understand that it is indeed a good book for a person who just started learning Python. Even how to install both on each operating system is very meticulous. Let me think of a sentence seen on the BBS, the book written by the foreigner, think the reader is idiot, and if the idiot understands ... Learn a language, or a technology, people may always use HelloWorld to demonstrate, However, Python should say that Dive Into Python did not let me down, give me an example won't let me feel that the page will turn that page. Master a language, the most basic should be Syntax and Semantics, then some data types. I learned a Python example today and then Native DataTypes. Among them, Python's grammar and syntax, through example to learn language, will never have more statements that are more than empty. DEF BuildConnectionsTRING (params): "" "Build a connection string from a dictionary of parameters. Returns string." "Return"; ". Join (["% s =% s "% (k, v) fork, v In params.Items ()]) The top is the first example I have learned, gave me different from Java, C / C feelings. Define a FUNCTION, the string started by the three quotes is this fuction's doc string, which is a property of the function, ending with three quotes. Does the parameter do not type? Correct! In the book, it is in Python, Variables Are Never Explicitly Typed. Python Figures Out What Type A Variable Is And Keeps Track of It ITNALLY. (I got some words on Notebook, I think it is useful to understand Python, I will Written a few Share) Don't pay attention to the type, is it easy? Thinking of the parameters of the function in JavaScript are not type.
