Python and Flask to build Rest API

Do you know Rest API? Certainly, yes. How about in Python? Follow this example to build two endpoints with Python and Flask.

First, we are going to install Flask:

pip3 install Flask

Now, create a file, for example, main.py:

from flask import Flask

app = Flask(__name__)

In the example above, we’re importing Flask and getting a reference to it. Now, add to the code:

@app.route('/info', methods = ['GET'])
def info():
    return 'This a simple endpoint to test and provides information about things.'

@app.route('/insert', methods = ['POST'])
def insert():
    return 'This a simple endpoint to test insert data.'

In the code above, @app is a decorator to create routes. The first argument is an URI. The second argument informs the HTTP Method. Finally, to execute:

if __name__ == '__main__':
    app.run(debug=True)

Running the code is:

python3 Main.py

and that’s all folks!
