I can teach you some Python language. It is one of the most popular programming languages, and is well suitable as the first one. It has three main application areas:
1) to create backend (i.e. the server side) for web sites and other services, such as mobile apps or chatbots;
2) to automate some routine tasks (e.g. scraping websites or updating numbers in some report);
3) to train and apply neural networks and other machine learning algorithms (for example, automatic machine translation, which is the thing that I do at my job).
In exchange, I would be happy if you helped me practice my spoken French.
