将模块列为字符串并将其导入 [英] list modules as strings and import them

问题描述

我有一堆需要导入的模块.由于某些原因，我不允许解释模块名称必须作为字符串存储在列表中.换句话说，我需要执行以下操作:

I have a bunch of modules that I need to import. For reasons I not permitted to explain the module names must be stored as strings in a list. In other words I need to do the following:

modules_to_import = ['module1', 'module2', 'module3']
import modules_to_import

有人知道我能否在python中做到这一点吗?

Does anybody know if I can to that in python?

推荐答案

使用importlib.import_module:

imported_modules = {m: importlib.import_module(m) for m in modules_to_import}

如果要将模块作为全局变量访问，则必须做一些棘手的事情，例如分配给globals():

If you want to access the modules as global variables, you'll have to do some hacky stuff, such as assigning to globals():

for module in modules_to_import:
    globals()[module] = importlib.import_module(module)
