from flask import Flask, render_template, request
from vsearch import search4letters

app = Flask(__name__)


@app.route('/')

    return 'Hello world from Flask!'


@app.route('/search4', methods=['POST'])

    letters = request.form['letters']
    title = 'Here are your results:'

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