Python - Modules and Code Organization

You have a module settings.py with a variable mode = 'default'. In your main script, you write:

import settings
settings.mode = 'custom'
import settings
print(settings.mode)

What will be printed and why?

A'default' because the second import resets the module

B'custom' because the module is cached and not reloaded

CError because variable reassignment is not allowed

D'default' because import always reloads the module

Step-by-Step Solution

Solution:

Step 1: First import
The module settings is imported and mode is set to 'default'.
Step 2: Variable reassignment
The variable settings.mode is reassigned to 'custom' in the main script.
Step 3: Second import
The second import settings does not reload the module but uses the cached module object, so the reassigned value remains.
Step 4: Print statement
Printing settings.mode outputs 'custom'.
Final Answer:
'custom' because the module is cached and not reloaded -> Option B
Quick Check:
Modules are imported once and cached [OK]

Quick Trick: Module imports are cached; reassigned variables persist [OK]
