from flask import Flask
from flask_compress import Compress

app = Flask(__name__)
Compress(app)

@app.route('/')

AThe response will be compressed if the client supports it

BThe response will always be uncompressed

CThe app will raise an error because Compress is not configured

DThe response will be compressed only for POST requests

Step-by-Step Solution

Solution:

Step 1: Understand default behavior of Flask-Compress
Flask-Compress automatically compresses responses if the client sends headers indicating support (like Accept-Encoding).
Step 2: Analyze the code snippet
The app initializes Compress with the app and returns a simple string. Compression will happen conditionally based on client support.
Final Answer:
The response will be compressed if the client supports it -> Option A
Quick Check:
Compression depends on client headers = A [OK]

Quick Trick: Compression happens only if client supports it [OK]

Common Mistakes:

MISTAKES

Assuming compression is always on
Thinking configuration is mandatory
Believing compression only works on POST
