Python3-无法在__import__对象上调用reload()? [英] Python3 - reload() can not be called on __import__ object?

问题描述

好吧，出于多种原因，我在Python2中使用时间最长的时间是s = __import__('parse')，现在我需要将某些项目转换为Python3(主要是由于SSL).

Ok so for a number of reasons, I've been using s = __import__('parse') for the longest time in Python2, now I sorta need to being my transitions to Python3 for certain projects (mainly due to SSL).

但是据我发现，Python3中没有reload()等价物. 只有一种选择:

But there's no reload() equivilant in Python3 as far as i've spotted. There's only one option:

import parse
parse.reload() #works

但是我真的非常需要它来工作:

But I really, really need this to work:

parse = __import__('parse')
parse.reload()

或

reload(parse)

关于如何使其在Python3中工作的任何想法?

Any ideas on how to get it working in Python3?

推荐答案

reload内置函数已移至Python 3.4中的importlib模块:

The reload built-in function has been moved to importlib module in Python 3.4:

In [18]: from importlib import reload

In [19]: reload?
Reload the module and return it.

The module must have been successfully imported before.

@JPaget在评论 reload() 函数已从 imp 移至 Python 3.4 + 中的模块.来自 Python 3.4中的新功能:

As pointed out by @JPaget in comments reload() function has been moved from imp to importlib module in Python 3.4+. From what's new in Python 3.4:

reload()功能已从imp移至importlib，作为 imp模块弃用

The reload() function has been moved from imp to importlib as part of the imp module deprecation
