Introduction to Python Programming

Introduction to Python | Python Programming Basics is a hands-on Python programming course that teaches students the essentials of Python scripting to a foundation level. This course leads the student from the basics of writing and running Python scripts to more advanced features such as file operations, regular expressions, working with binary data, and using the extensive functionality of Python modules. Extra emphasis is placed on features unique to Python, such as tuples, array slices, and output formatting.

This Python training course provides an excellent kick start for users new to Python and scripting, enabling them to use basic Python skills on the job in a variety of ways.  Students can apply the course skills to use Python in basic web development projects or automate or simplify common tasks with the use of Python scripts. The course also serves as a solid primer course / foundation for continued Python study in support of next-level web development with Python, Python for data science / machine learning, or Python for systems admin or networking support.

This course is about 50% hands-on lab to 50% lecture ratio, combining engaging, informed instructor presentations, demonstrations, and discussions with extensive machine-based student labs and practical project work. Throughout the course, students will learn to write essential Python scripts using the most current and efficient skills and techniques.
