How do I handle query parameters in Flask?

In Flask, you can access query parameters using the request.args object. For example, if you have a URL like /search?query=flask, you can get the value of query with request.args.get('query').

Can you show me a code example?

Sure! Here's a simple example:

from flask import Flask, request

app = Flask(__name__)

@app.route('/search')
def search():
    query = request.args.get('query')
    return f'Searching for: {query}'

What if I have multiple query parameters?

You can access multiple query parameters in the same way. For example, if you have /search?query=flask&sort=asc, you can get both values using:

query = request.args.get('query')
sort_order = request.args.get('sort')

Is there a way to set default values for query parameters?

Yes! You can set default values by providing a second argument to get(). For example:

query = request.args.get('query', 'default_value')
