from flask import render_template 
from flask import Flask 
from flask import request 
from flask import jsonify 

app = Flask(__name__) 

@app.route('/') 
def home(): 
    return render_template("index.html") 

@app.route('/graph', methods=['POST']) 
def graph(): 
    fchoice = request.form['user'] 
    schoice = request.form['password'] 
    return choice + " " + choice 

и вот HTML в index.html:

<form action="/graph" method="post"> 
    <input type="text" placeholder="first choice" name="user" disabled id="chose"> 
    <input type="text" placeholder="second choice" name="password" disabled id="chose1"> 

    <input type="submit" value="Vote"> 
</form> 

Answer 1

Вы пытаетесь объединить неопределенные переменные.

return choice + " " + choice 

У вас нет choice. У вас есть fchoice и schoice.

@app.route('/graph', methods=['POST']) 
def graph(): 
    fchoice = request.form['user'] 
    schoice = request.form['password'] 
    return fchoice + " " + schoice
