Return JSON response from Flask view

I have a function that analyzes a CSV file with Pandas and produces a dict with summary information. I want to return the results as a response from a Flask view. How do I return a JSON response? @app.route("/summary") def summary(): d = make_summary() # send it back as json
A view can directly return a Python dict or list and Flask will call jsonify automatically. @app.route("/summary") def summary(): d = make_summary() return d For older Flask versions, or to return a different JSON-serializable object, import and use jsonify. from flask import jsonify @app.route("/summary") def summary(): d = make_summary() return jsonify(d)
