¿Necesita importar Python de excepción?

Do you need to import exception Python?

The exceptions module provides the standard exception hierarchy. It’s automatically imported when Python starts, and the exceptions are added to the _ _builtin_ _ module. In other words, you usually don’t need to import this module.

When a module is first imported, Python searches for the module and if found, it creates a module object 1, initializing it. If the named module cannot be found, a ModuleNotFoundError is raised. Python implements various strategies to search for the named module when the import machinery is invoked.

There are a lot of other uses for exceptions besides handling actual error conditions. A common use in the standard Python library is to try to import a module, and then check whether it worked. Importing a module that does not exist will raise an ImportError exception.

I don’t think try except block is un-pythonic; instead it’s a common way to handle import on Python. There are a lot of other uses for exceptions besides handling actual error conditions. A common use in the standard Python library is to try to import a module, and then check whether it worked.

Set up exception handling blocks. To use exception handling in Python, you first need to have a catch-all except. clause. The words “try” and “except” are Python keywords and are used to catch exceptions. try-except [exception-name] (see above for examples) blocks. Recommended Python Training.

Sometimes you don’t need all module functions but only need one single part. Then you can import only a small part of modules with from … import … statement As we know, sys modules controls Python interpreter environments. And I only wanted to check function call recursion limit in my ipython environment.
