从 Python 中的另一个文件导入变量

Question

I have two files - abc.py and main.py . My aim is to import the whole dictionary from another file. To explain it better, a user enters a input(lets say English) and this should be import variable English from the abc.py into main.py . Below is the code I tried, it's giving me an error.

*/abc.py

English = {1:"Hello", 2:"World"}
Italian = {1:"Bonjour", 2:"Mondo"}

*/main.py

import abc
option=input("Please Enter 'English' or 'Italian': ")
selectedLanuage = abc.option

print(selectedLanuage)

Answer 1

One workaround I can think of is separating the access of the dictionary and the input.

option=input("Please Enter 'English' or 'Italian': ")
if option == "English":
    selectedLanguage = abc.English
elif option == "Italian":
    selectedLanguage = abc.Italian
print(selectedLanguage)

EDIT:

languages = {"English": abc.English, "Italian": abc.Italian}
option = input("Please Enter 'English' or 'Italian': ")
selectedLanguage = languages[option]

Answer 2

First, I highly recommend you name your current abc file something else since abc is actually a standard library module . Assuming you have the following in languages.py

English = {1: "Hello", 2: "World"}
Italian = {1: "Bonjour", 2: "Mondo"}

and the following in main.py

from languages import English, Italian

languages_by_choice = {
    'English': English,
    'Italian': Italian
}

option = input('Please enter "English" or "Italian": ')
selected_language = languages_by_choice.get(option)
if not selected_language:
    raise ValueError('Invalid language selection: {}'.format(option))

print(selected_language)

your program would be used something like this:

~ python3 main.py   
Please enter "English" or "Italian": English
{1: 'Hello', 2: 'World'}

~ python3 main.py
Please enter "English" or "Italian": Italian
{1: 'Bonjour', 2: 'Mondo'}

~ python3 main.py
Please enter "English" or "Italian": asdf
Traceback (most recent call last):
  File "stackoverflow.py", line 11, in <module>
    raise ValueError('Invalid language selection: {}'.format(option))
ValueError: Invalid language selection: asdf
