Python is an object oriented rapid development language deployed in many scenarios in the modern world. This Python programming 1 course is designed to give delegates the knowledge to develop and maintain Python scripts using the current version (V3) of Python.
Course overview:
There are many similarities between Python V2 and Python V3. The skills gained on this course will allow the delegate to develop their own skills further using Python V2 or V3 to support the development and maintenance of scripts. The Python programming 1 course comprises sessions dealing with syntax,variables and data types, operators and expressions, conditions and loops, functions, objects, collections, modules and packages, strings, pattern matching, dates, exception handling, files and databases. Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.
Course objectives:
This course aims to provide the delegate with the knowledge to be able to produce Python scripts and applications that exploit all core elements of the language including variables, expressions, selection and iteration, functions, objects, collections, strings, modules, pattern matching, exception handling, I/O and classes.

Target audience:
The Python programming 1 course is aimed at anyone who wants to learn Python as a first language, and developers / engineers who want to migrate to Python from another language, particularly those with little or no object-oriented knowledge.
Prerequisites:
• Delegates attending this course should have some previous programming experience and be able to define general programming concepts including: compilation,execution,variables,arrays,sequence,selection,iteration,functions,objects,and classes.
Moreover delegates should be able to navigate the filesystem (on the command line ideally),edit and save text files and browse the web. This knowledge can be obtained by attendance on the pre-requisite Introduction to Programming course.
