This one day course is designed for data scientists and engineers who are already using Python and want to take their skills to the next level. At the end of this course the students will know how to structure their Python programs for improved reuse, how to build and use automated tests for their code, and how to analyze program performance. The class will use Python 3. We start by covering ideas and concepts for improving overall software design . We then explore how these ideas can be applied to a small but realistic Python project. We will look at techniques and best-practices for working with Python projects in groups Key topics • Software design principles• Managing dependencies in software• Isolating development environments• Packaging code for reuse• Documentation and style• Automated testing• Profiling programs• Strategies and techniques for optimization• Maintaining invariants and constraints• Creating command-line interfaces• Sharing code with package servers Course exercises • Creating isolated environments with venv or conda Applying core software design principles• Following Python best-practices• Using a practical and flexible project structure• Building packages from your code• Documenting your code in a standard way• Creating and running automated tests• Using a profiler to find performance problems• Optimizing your code based on profiling data• Uploading packages to a package server• Using your own packages from a package server Bring your own computer with Python 3.3+ and an editor installed.  [-]

Python is an object oriented rapid development language deployed in many scenarios in the modern world. [+]
COURSE OVERVIEW   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. 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,exception handling,binary and text files,and databases. Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered. TARGET AUDIENCE The Python Programming 1 course course is aimed at those who want to improve their Python programming skills,and for developers/engineers who want to migrate to Python from another language,particularly those with little or no object-oriented knowledge. For those wishing to learn Python and have no previous knowledge of programming,they should look to attend our foundation course Introduction to Programming - Python. 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.
