Why Learn Python? Watch the video now!
Python is a general purpose programming language that was designed to be compact, easy to use, easy to extend, and which has a large standard library and a very active development community. As well as being a general purpose programming language, Python is widely used as a scripting language, a glue language, for data science and machine learning, and for software test.
Essential Python is intended for professionals working in the electronic systems hardware and embedded software development flows. The training is for people who need to learn Python quickly to get a specific job done. It focusses on the most commonly used features of the Python language and teaches you all you need to know to start using Python properly and effectively.
Workshops comprise approximately 50% of class time and are based around carefully designed hands-on exercises to reinforce learning.
Essential Python is a hands-on programming course aimed at software, hardware, and support engineers who need to use Python for scripting development and tool flows, for hardware verification, for software test, for data science and machine learning, or for running Python on embedded devices.
This course assumes you already know how to write computer programs. Delegates should have a good working knowledge of at least one programming language or hardware description language, suitable examples being C, C++, Java, Perl, VHDL, or SystemVerilog. An understanding of object-oriented programming would be beneficial, but is not absolutely essential.
This course is not suitable as an introductory course in computer programming, that is, this course does not teach Python as a first programming language. Please contact Doulos direct to discuss and assess your specific experience against the pre-requisites.
