python sys.modules Python中所有加载到内存的模块都放在sys.modules。sys.modules是一个全局字典,字典sys.modules对于加载模块起到了缓冲的作用,当import一个模块时首先会在这个列表中查找是否已经加载了此模块,如果加载了则只是将模块的名字加入到正在调用import的模块的Local名字空间中。当第二次再导入该模块时,python...

There are several places where MINGW-packages patches to python check if the string "GCC" is in sys.version, to switch between 'normal' windows python behavior and the 'posix build'. In this case, the sys.version string says "Clang" instead of GCC. Member Author jeremyd2019 commented Jan...
sys 模块可以让你访问解释器相关参数,比如模块搜索路径,解释器版本号等.operator模块提供了和内建操作符作用相同的函数.copy模块允许 你复制对象, Python 2.0 新加入的gc模块提供了对垃圾收集的相关控制功能. 1.2. _ _builtin_ _ 模块 这个模块包含 Python 中使用的内建函数. 一般不用手动导入这个模块; Python会帮...
Namespaces, classes, and using standard modules Jul 18 '05, 01:33 AM I have several simple classes which need to us "standard" modules like os and sys A class might look like: # --- MyClass.py --- class MyClass: def __init__ (self): self.data = '' self.data2 = 'mydata...
The re module provides regular expressions support for Python. Regular expressions are string patterns written in a special syntax, which can be used to match strings and extract substrings. Language Support Modules sys gives you access to various interpreter variables, such as the module search ...
