其实不然，如下例：import inspectimport osprint(inspect.getsource(os)[:10])>>>r"""OS rou成功获取，但是，如果要想知道其中某一方法的实现，就会抛出TypeError异常，如下print(inspect.getsource(os.getcwd))异常如下>>>TypeError: module, class, method, function, traceback, frame, or code object was ex...
直接写模块名称会出现报错:reload() argument must be a module 看下reload()的相关源码说明:传的module参数必须在使用之前被成功导入过。 def reload(module): """Reload the module and return it. The module must have been successfully imported before. """ if not module or not isinstance(module, typ...
The first obvious reason for this is, in wildcard imports, the names with a leading underscore don't get imported. This may lead to errors during runtime. Had we used from ... import a, b, c syntax, the above NameError wouldn't have occurred. >>> from module import some_weird_...
因为inspect.getargspec在 3.11+ 中已弃用。 翻看源码如下图 解决方案: 解决方法是使用inspect.fullargspec代替,并添加 3 个虚拟变量,因为 getfullargspec 将返回 7 个项目而不是 4 个: args, varargs, keywords, defaults, foo, foo1, foo2 = inspect.getfullargspec(func) ...

In particular, it’ll look in a module cache to see if something has already been imported, and it’ll search among the built-in modules. You’ll learn more about the full Python import machinery in a later section. You can inspect Python’s import path by printing sys.path. Broadly ...
