![]() Python keeps track of what belongs to the function by checking for indentation. In this case your group will be very small, just one instruction. The game is very simple, Alice says out an integer and Bob has to say whether the number is prime or not. On the next line you’ll give this function its group of instructions. The operating system defines how the program should write so that it can be converted to machine language and the system takes appropriate action. To define a function we need to use the “def” keyword, give it a name, a set of parentheses and end the line with a colon so your function will start like this: def hello_world(): The most basic way to describe a function is as a named group of instructions which can be reused whenever we call it by name. Your first order of business is to define a function. Other software packages called programming tools help programmers write programs by providing program creation and editing facilities. ![]() ![]() write('Please enter your name: ') local username read() print('Hello ', username, '.') Save and exit the editor, then execute the program. Procedural Oriented programming language is used by a software programmer to create a program that can be accomplished by using a programming editor like. When Python executes your program it will read instructions, one line at a time from the start of the program to the end of the program. Open a new program file in the editor (recommended name: hello2 ). Low-level languages are simple, but considered difficult to use, due to numerous technical details that the programmer must remember. An equivalent program in a high-level languagecan be less efficient and use more memory. The process starts with software engineers designing a program, and then the. However, using a software application (specifically designed for coding in a particular. Computer programmers write code for programs that will be on computers. It’s time for you to write your program! You can hardly call yourself a programmer without writing a “hello world” program. A program written in a low-level language can be made to run very quickly, with a small memory footprint. One can write a simple code with a basic word processor or text editor.
