import os
from flask import Flask, render_template, redirect, url_for, session, request, flash, abort, Markup

from sybload import funcs, forms

app = Flask(__name__)
app.debug = True
app.config['SECRET_KEY'] = os.urandom(24)
app.config['CSRF_ENABLED'] = True
bootstrap = Bootstrap(app)

dataserver_info = funcs.get_dataserver_info()
dataservers = funcs.get_dataservers(dataserver_info)

@app.route('/', methods=['GET', 'POST'])
def root():
    session.clear()
    form = forms.DataServersForm()
    form.dataserver.choices = zip(dataservers, dataservers)
    if form.validate_on_submit():
        session['dataserver'] = form.dataserver.data
        # print statement below never runs
        print …
