I’m trying to do simple comparison. I want to compare whether or not a transaction from exceeds a value from a sql database. Yet when I compare it. I get the following issue.

TypeError: '<' not supported between instances of 'list' and 'float'

I referenced the other post List comprehension and “not supported between instances of ‘list’ and ‘float” but I’m not sure whether using the filter function would be suitable since it needs a function and a sequence. Any advice? I included my program below:

    symbol = request.form.get("symbol")
    stock_shares = request.form.get("shares")

    #Identifies time of purchase
    currTime = time.ctime()

    # Yahoo Query for valid stock. Stores values in variables
    info = lookup(symbol)
    stock_symbol = info.get("symbol")
    stock_price = info.get("price")

    # Retrieves user data
    user_cash = db.execute("SELECT cash FROM users WHERE id IN (?)", session["user_id"])
    print("User cash: ", user_cash)

    if user_cash < transactionTotal:
        return apology("Insufficient funds, 403")

TypeError: ‘<‘ not supported between instances of ‘list’ and ‘float’
