To find out the cost of software development

How much would it cost to revise the program? The program is written in python and allows you to parse data from any website for a certain key. There are some more minor functions that need to be added.

It all depends on how you negotiate with the developer. It is easier to seek the services of freelancers. They should be able to do this kind of work. But there is a disadvantage in that it is a revision of a program that is already ready.

What's the problem? Is it the language in which you need to complete the programme? Or is it something else? It doesn't look like there is much work to be done. So I don't think there should be any difficulties.

hmm

It would be much more difficult for any programmer to complete a program which has been written by another developer. Usually experienced developers should take on this kind of work. The cost of development will be higher accordingly. But your task will be completely solved.
