importpkgutil# 使用pkgutil.iter_modules()函数迭代已安装的模块formoduleinpkgutil.iter_modules():print(module.name) 1. 2. 3. 4. 5. 这段代码将输出Python中已安装的所有模块的名称。 总结 通过以上步骤,我们成功地实现了“python list modules”的任务。我们首先导入pkgutil模块,然后使用pkgutil.iter_modules(...
In addition to normal directories, individual PYTHONPATH entriesmay refer to zipfiles containing pure Python modules (in either source orcompiled form). Extension modules cannot be imported from zipfiles. The default search path is installation dependent, but generally begins withprefix/lib/pythonversio...
NoSQL database modules enable Python applications to work with non-relational databases that store data in flexible formats. These modules support various data models including document stores, key-value pairs, wide column stores, and graph databases, each optimized for specific use cases and scaling...

sys.path是python的搜索模块的路径集,是一个list 可以在python 环境下使用sys.path.append(path)添加相关的路径,但在退出python环境后自己添加的路径就会自动消失了! 可以使用以下命令输入当前python 的搜索路径: python -c"import sys;print '当前的python是:'+sys.prefix;print '\n'.join(sys.path)" ...
modules[__name__] # sys.modules stores imported modules >>> current_module.__dict__ is globals() True 当前模块(current module)就是 Python 代码执行时所在的命名空间。引入一个 Python 文件时,Python 会创建一个新的模块对象,并在执行该文件代码的时候,将该模块对象的字典作为全集变量。类似地,直接...
