燒瓶從字段中保存選定的值並在另一頁上顯示

我是新來的燒瓶，並且遇到困難，保存從四種不同的咖啡烘焙選項中選擇的值並將其顯示在另一頁上。一個頁面（Roast.html）用戶可以選擇從Light，Medium，Dark和Special中選擇一個咖啡烘焙。按下提交按鈕後，我想在下一頁（Brew.html）上顯示該選擇，即「你的_____烘焙咖啡現在正在釀造！」任何幫助將不勝感激！我寧願不在這個代碼中涉及php或javascript。謝謝燒瓶從字段中保存選定的值並在另一頁上顯示

def roast(): 
    print "inside Roast" 
    return render_template("Roast.html")

你只需要從request.form對象搶元素：

if request.method == 'POST': 
    brew_type = request.form["roastType"] 
    print(brew_type) 
    return render_template("Brew.html", selection=brew_type)

它涵蓋的所有quickstart guide。
