- 10. • A computer programming language is a set of commands that tell a computer how to perform tasks. Programming languages include: • Java: Used for enterprise-level applications • Python: Used for data analysis and machine learning • JavaScript: Used for web development • C++: Used for system-level programming • Ruby: Used for web development • SQL: Used for specifying the organization of databases • HTML: Used for front-end development • CSS: Used for front-end development (Bjarne Stroustrup. 1985 ) • React: Used for front-end development
- 11. Importance • Computer programmers use programming languages to write, test, and maintain code. These essential tech professionals are some of the best coders in the world that create programs and software that millions of people use every day.
- 12. History of Computer Programmers • The origins of programming languages and computers trace back to the early 19th century. Computing pioneers like Charles Babbage and Ada Lovelace paved the way for mid-20th-century developers such as John Von Neumann, Grace Hopper, and John W. Backus • Machine language, compiler languages, and source codes preceded modern computer programming. The computer programming profession grew alongside emerging programming languages like C in 1972, C++ in 1983, and Python in 1991.
- 13. What Does a Computer Programmer Do? • Computer programmers use programming languages to write, revise, test, and update code. This code allows computers, software, and applications to carry out tasks. • Because technology pervades diverse sectors, computer programmers also work across industries. After the tech industry, finance, insurance, and manufacturing entities hire the most computer programmers. • Computer programmers often work alone, spending long hours in front of their screens. These professionals also collaborate with software developers and engineers. Writing, testing, and debugging code can take many attempts. Still, computer programmers persevere, and many enjoy a good challenge. • Find out more about key skills that influence success as a computer programmer below.
- 14. What is code? • Code is the language that all computers "speak" and understand. When computer programmers write code, they issue instructions to a computer and tell it which actions to perform and in what order. They use different programming languages to communicate with specific systems. • Computer code is comprised of strings of typed letters, numbers and figures which constitute a language, complete with spelling rules and syntax. Someone who knows how to program or write code can pursue a variety of career paths since code is used for a range of activities, from building websites to flying airplanes. Anything that you can do that involves a computer functions because of code.
- 15. Why is writing code important? • Code is used for websites, cars, televisions, cellphones, airplanes, gaming consoles and thousands of other products. The need for skilled computer coders continues to grow as more companies are producing "smart" or computer-equipped merchandise. To keep up with the demand for computerized items, manufacturers need innovative and dedicated coders to write quality code for new products. The ability to read and write is an incredibly useful skill and can greatly increase your value as a team member or employee.
- 16. Responsibilities • Writing Code, Scripts, And Programs: Computer programmers use programming and scripting languages like Java, Python, Ruby, and JavaScript to write code. They apply program designs, use models, and integrate algorithms to ensure software runs properly and efficiently. • Check icon Testing Code, Scripts, And Programs: To test code, scripts, and programs, computer programmers check for simple text, review code, and run programs for functionality purposes. Testing also involves working with fellow programmers to determine coding solutions. • check icon Updating Applications: Updating and adding to programs includes altering and building new code while making sure the changes work properly.
- 17. • Check icon Analyzing Efficiency: Efficient code improves collaboration and keeps memory issues from arising. Along with functional code, computer programmers ensure that their work is clean and effective. • Check icon Collaborating: Computer programmers work with developers and designers to determine the overall goal, look, and function of a program. Collaboration requires written and verbal communication in meetings and brainstorming sessions throughout the development process.
- 18. Computer Programmer • Computer programmers spend much of their days behind computers writing code, scripts, and programs. Their code may apply to new software or existing applications. Computer programmers make changes to code and scripts, find solutions, and provide technical support. Common computer programming languages include Python, Java, and C+.
- 19. • Computer programmers are problem-solvers who create and update programs for software developers and engineers. They must remain dedicated to presenting products that meet users' needs and goals.
- 20. Skills for Computer Programmers • plus-circle icon Communication Skills: Computer programmers must explain complex technical concepts to their colleagues and to people without technical backgrounds. • plus-circle icon Multitasking: Computer programmers often work on many tasks at once or on parts of a larger project. Programmers must organize their priorities, solve problems as they arise, and carry out several duties at once. • plus-circle icon Organizational Skills: Organizational skills include the ability to focus, budget mental and physical energy, and manage time effectively.
- 21. • plus-circle icon Attention to Detail: Coding errors can cause projects to run over schedule and budget. A detail- oriented attitude helps programmers catch mistakes and write efficient, usable code.
- 22. • plus-circle icon Programming Languages: Programmers need to excel in at least one programming language like Python, Java, or C++. Ideally, computer programmers should know multiple languages and understand how and when to use each one. • plus-circle icon Software Development: Because computer programmers take part in software development, they need to know the development process. Software development involves identifying, designing, and implementing software requirements. From there, computer programmers verify and maintain software.
- 23. • plus-circle icon Data Structures and Algorithms: Data structures are formats for organizing, processing, retrieving, and storing data for efficient access. Algorithms are collections of steps to solve specific problems. Computer programmers use algorithms to search, organize, and retrieve data in data structures. • plus-circle icon Databases: Computer programmers use programming languages to coordinate, maintain, and update information in databases like Oracle and MySQL. They may write, test, and implement code for new databases.
- 24. • Creating simple Python applications can be a great way for beginners to learn programming concepts and build their confidence in coding. Below, I will guide you through the creation of three simple Python applications, including a command-line calculator, a basic to-do list, and a number guessing game. Each app will include a clear explanation of the code and concepts involved.
- 25. Distinguishing Keywords from identifiers • keywords are reserved words in Python.They are use to define the syntax and structure.
- 26. 1. Command-Line Calculator Overview • This calculator can perform basic arithmetic operations like addition, subtraction, multiplication, and division. Code • def add(x, y): def multiply(x, y): • return x * y • def divide(x, y): if y == 0: return "Error! Division by zero." return x / y
- 27. • def calculator(): • def subtract(x, y): • return x - y • calculator()
- 28. Getting started with the python • Python is an interpreted, object- oriented, high level programing language Guido van Rossum - published the first version of Python code(1991) 1994-python 1.0 was released 2000- python 2.0 was introduced and flourished for another 8 years in the 2.x series. Python 3.0 removed duplicate programming construction and modules.

Editor's Notes
- #18: Many computer programmers are self-employed. Others work in office settings at computer systems design companies, financial and insurance institutions, manufacturing businesses, and software publishing firms. Computer programmers may work remotely or participate in face-to-face activities but generally spend 40 hours a week on the job
- #19: Computer programmers work closely with software and application designers, developers, and engineers. They meet with colleagues throughout a typical workday and may present their work to stakeholders to demonstrate progress.
