12.动态导入(Dynamic Importing) 你可以使用importlib模块动态导入模块。这在你想要根据用户输入或配置导入模块时非常有用。 import importlib module_name = 'math' module = importlib.import_module(module_name) result = module.sqrt(9) print(result) ...
对于动态语言与静态语言的区分,套用一句流行的话就是:Static typing when possible, dynamic typing when needed。 强类型语言 强制数据类型定义的语言。也就是说,一旦一个变量被指定了某个数据类型,如果不经过强制转换,那么它就永远是这个数据类型了。因此强类型定义语言是类型安全的语言。
This feature makes it possible to handle large data stream, OpenAI integrations, deliver dynamic content, and support other core HTTP scenarios requiring real-time interactions over HTTP. You can also use FastAPI response types with HTTP streams. Without HTTP streams, the size of your HTTP requests...

regardless of whether it is a call to the built-in function eval or not. Due to the dynamic nature of Python, such syntactic queries can be inaccurate. If one is looking for invocations of the built-in function eval, it is preferred to use the API graph, see “Using API graphs in Py...
