Python Training Course

Who should attend

Python is the most popular language around today with many organisations using it for a wide variety of purposes from developing web sites, implementing DevOps functions to Machine Learning and Data Analysis. This course is ideal for any Software developer who wants to be able to develop modern Python applications or services.

Prerequisites

You should have some previous programming experience in another language such as Java, JavaScript, Perl, PHP, C# or C++. No previous Object-Oriented Programming is assumed but would be a bonus!

On-site

We would be happy to discuss custom / on-site Python training for any size of team. We can take into account your existing technical skills, project requirements and timeframes, and specific topics of interest to tailor the most relevant and focussed course for you.

This can be particularly useful if you need to learn just the new features and Python programming Best Practices, or need to include extra topics to help with pre-requisite skills. If you would like to dicuss your custom training requirements, please get in touch.
