如何在 Python 中循环以下代码？

Question

I am new to Python but I tried to create the following trading strategy but cannot find a way to loop it for different products (trading hours in this case).

def strategy(area_code, product, orders, environment):
    order = None
    new_orders = [] 
    Quantity = 5
    price_delta = 0.1

    def process_flex(Plant):

        order = None
        Tur1 = Plant + "1"

        if Tur1Volume > 0:
            if Tur1Price:
                order = None
                if check_if_we_have_order_on_the_market(Plant,Tur1)==0:
                    order =  package.create_sell_order(area_code, Tur1Volume, Quantity, calculate_selling_price(Tur1Price), price_delta, product, environment.current_datetime).with_label((Plant,Tur1))
                if order:
                    new_orders.append(order)
            else:
                order = None

        return 

    process_flex("bla")
    process_flex("blabla")
    process_flex("blablabla")


    return new_orders

This code is only working for one product (1 hour) and does not loop for all 24 products. I thought that it could work like this:

    for product in products:
        Plant = ['bla', 'blabla', 'blablabla']
        for i in Plant:
            order = process_flex(Plant)
        return_orders.append(order)

    return return_orders      

Unfortunately, it did not work. Do you have any idea on the solution?

Thank a lot in advance!

Answer 1

You want to swap Plant to : order = process_flex(i) because i is an element of Plant

    for product in products:
        Plant = ['bla', 'blabla', 'blablabla']
        for i in Plant:
            order = process_flex(i)
        return_orders.append(order)

    return return_orders
