Learning Objectives- Understand the importance of using correct data types: string, integer or float Learning Objectives Be able to write a program in Python Learning Outcomes All To know what main data types are and what a variable is in programming how to use assignment statements correctly Why are you learning about this? Understanding how computers are used and should work is extremely vital. Python is a powerful but easy-to-use high-level programming language. It is important that you understand the process of developing programs, the importance of writing correct syntax, being able to formulate algorithms for simple programs and debugging their programs. Programming is used to create all the games, social media and apps you use in your daily life. Computer systems engineers are responsible for identifying solutions to complex applications problems, systems administration issues or network concerns. They work closely with clients or internal stakeholders to understand system needs and collaborate with developers to determine appropriate solutions. This is another programming career that is ideal for business-savvy professionals.
