You can pass it to a function like this (the code of one of the www.habr-analytics.com/user functions )

@app.route('/userfig/<name>/<datatype>')
def userfig(name,datatype):
  name = str(name.strip().lower())
  # unsupported operation
  if datatype not in datatypes:
    return
    .....

You can pass back to the form as follows (from the same place)

@app.route('/user/', methods=['GET'])
def user():
  name = request.args.get('name')
  datatype = request.args.get('datatype')
  data_title = None
  if datatype in datatypes:
    data_title = datatypes_to_title[datatype]
  return render_template("user.html", usernameform=usernameform, name=name, datatype=datatype, datatypes=datatypes, data_title = data_title)
