Python Fundamentals Training for Non-Programmers

This hands-on course is intended for those individuals with little or no software development experience. Starting with the most fundamental elements, this training evolves your skills to produce complete computer applications including the user interface, business logic and data access layers. During the course, attendees will write code using Python, one of the most popular modern languages and highly suitable for beginners. In addition, comparisons with other languages such as Java and C# will be discussed. Development techniques include requirements, design, code generation, testing and debugging. You gain all the pre-requisite skills necessary to carry on to more language-specific training appropriate for the type of applications needed by your organisation be they data science, web development, embedded real-time systems or other.

Key Features of this Python Fundamentals Training for Non-Programmers:

  • After-Course Instructor Coaching
  • Hands-On Labs Included
  • End of course Exam available at the end of class.
