从变量文件导入的Python

Question

I am new to python i want to use

from variablefile import *

i need to take variablefile as a input from user.i tried to use raw_input() but it didn't work, is there any way in python to do this?

Answer 1

from ... import * is not really good practice as it can cause name conflicts and makes it harder to see where classes etc. are really defined. This would especially be the case if you are accepting ... from the user input

import importlib
globals().update(vars(importlib.import_module(variablefile)))

Answer 2

Try:

myvar = "os"
eval("import %s" % myvar)
