Syntaxe non valide CS50 Finance

Question

j'obtiens une erreur de syntaxe dans mon code:

if request.method == "POST": 
    quote = lookup(session["symbol"]) 
    name = quote["name"] 
    price = float(quote["price"]) 

    amount = db.execute("SELECT cash FROM users WHERE id=:user_id", user_id = session["user_id"]) 
    amount = float(amount[0]["cash"]) 

    if (int(request.form.get("number")) * price) >= amount: 
     return apology("You do not have enough money.") 

    new_amount = db.execute("UPDATE users SET cash = cash +: cost WHERE id =: user_id", user_id = session["user_id"], cost = quote["price"] * int(request.form.get("number")) 
    db.execute("INSERT into history (userID, stockSymbol, stockName, price, amount, buySell) VALUES (:userID, :stockSymbol, :stockName, :price, :amount, 1)", userID = session["user_id"], stockSymbol = session["symbol"], stockName = name, price = quote["price"] * int(request.form.get("number"), amount = int(request.form.get("number"))) 

    return redirect("") 

else: 
    return render_template("buy.html")

C'est là l'erreur de syntaxe se produit:

db.execute("INSERT into history (userID, stockSymbol, stockName, price, amount, buySell) VALUES (:userID, :stockSymbol, :stockName, :price, :amount, 1)", userID = session["user_id"], stockSymbol = session["symbol"], stockName = name, price = quote["price"] * int(request.form.get("number"), amount = int(request.form.get("number")))

Quelqu'un pourrait-il expliquer une raison possible pourquoi?

Answer 1

Vous manquez la parenthèse sur ce morceau de code quote["price"] * int(request.form.get("number"))

Votre deuxième erreur est aussi un échec de la parenthèse sur cette ligne db.execute("UPDATE users SET cash = cash +: cost WHERE id =: user_id", user_id = session["user_id"], cost = quote["price"] * int(request.form.get("number")))
