Getting Started Tools and Toys This part provides some necessary background to help non-programming newbies get ready to write their own programs. We’ll start with the big picture. In Let There Be Python: Downloading and Installing we’ll describe how to install Python. We’ll describe two typical problems that Python can help us solve in Two Minimally-Geeky Problems : Examples of Things Best Done by Customized Software.

We also provide some history and background to help show why Python is so cool. Arithmetic and Expressions Before Reading and ‘Riting comes ‘Rithmetic The heart of Python is a rich variety of numeric types and arithmetic operators. Ctypes tutorial. Note: The code samples in this tutorial uses doctest to make sure that they actually work. Since some code samples behave differently under Linux, Windows, or Mac OS X, they contain doctest directives in comments. Note: Quite some code samples references the ctypes c_int type. This type is an alias to the c_long type on 32-bit systems. So, you should not be confused if c_long is printed if you would expect c_int - they are actually the same type. ctypes exports the cdll, and on Windows also windll and oledll objects to load dynamic link libraries.

You load libraries by accessing them as attributes of these objects. cdll loads libraries which export functions using the standard cdecl calling convention, while windll libraries call functions using the stdcall calling convention. oledll also uses the stdcall calling convention, and assumes the functions return a Windows HRESULT error code. Windows appends the usual '.dll' file suffix automatically. Python Tutorial.

Python Mind, Beginner’s Mind. The practice of Zen mind is beginner’s mind.

Python Mind, Beginner’s Mind

The innocence of the first inquiry“what am I?” Is needed throughout Zen practice. The mind of the beginner is empty, free of the habits of the expert, ready to accept, to doubt, and open to all the possibilities. It is the kind of mind which can see things as they are, which step by step and in a flash can realize the original nature of everything. 10 Python one liners to impress your friends « /code/blog.

Without much ado.. here goes. Note that the variable declarations and imports are on separate lines as necessary. Also every line is written so as to print out the results to stdout for quick verification For what it is worth, this hardly took any time - this post is probably one of the quickest I have written. 1. Multiple Each Item in a List by 2. Python. You have seen how you can reuse code in your program by defining functions once.


What if you wanted to reuse a number of functions in other programs that you write? As you might have guessed, the answer is modules. There are various methods of writing modules, but the simplest way is to create a file with a .py extension that contains functions and variables. Another method is to write the modules in the native language in which the Python interpreter itself was written.
