Python comes with a library of standard modules, described in a separate document, the Python Library Reference (“Library Reference” hereafter). Some modules are built into the interpreter; these provide access to operations that are not part of the core of the language but are nevertheless bui...
如果我们查看一个namespace package的__path__属性,会发现它保存了所有匹配其名字的package,而一个regular package(比如这里import的xml)的__path__属性只会保存一个路径,在sys.modules中import进来的同名的package也会单独记录 >>> spam.__path__ _NamespacePath(['spam_foo\\spam', 'spam_bar\\spam']) >...

Guido van Rossum developed Python based on the defunct ABC programming language and named it after the Monty Python comedy troupe. Python was designed to be simple, readable, and highly extensible through the use of modules. The first version of Python was released in 1991, and the more fully...
Without the if-check, the Python interpreter would see executable statements in the imported modules and execute them. Put slightly differently, if you add the if-check to your program-defined Python files, these files can be imported by other Python programs and won’t cause trouble. So, ...
Pygame - Pygame is a set of Python modules designed for writing games. PyOgre - Python bindings for the Ogre 3D render engine, can be used for games, simulations, anything 3D. PyOpenGL - Python ctypes bindings for OpenGL and it's related APIs. PySDL2 - A ctypes based wrapper for the ...
The output of this command will show a list of locations (directories) on your disk where the operating system looks for executable programs. Depending on your system, locations can be separated by a colon (:) or a semicolon (;).
4. Running functions and modules: In Python, you can define functions and modules, which encapsulate blocks of reusable code. To run a function, you need to call it by its name followed by parentheses. For example, if you have a function named “my_function”, you can run it by typing...
package them as a file, and you’ve got amodule(which can also be reused). It’s true what they say:it’s good to share, and by the end of this chapter, you’ll be well on your way tosharingandreusingyour code, thanks to an understanding of how Python’s functions and modules ...
