Document Summary

Van rossum designed a simpler syntax (language) to create programs quickly and make them easy to modify. Python programs are executed by python interpreter which reads & executes it. Ide (integrated development environment): to create a comp program. Python interpreter reads program and executes all the steps. Ide components: source code editor helps programming by listing line numbers of code, color lines of code (comments/text), auto ident source code, output window, debugger. Compiler reads program & generates byte code instructions (simple instructions for the. Reads source code & compiles it into byte code. Comment: #statement that provides info to programmer without displaying on output screen: compiler ignores comments, courtesy to humans who read your code. Editor is a program for entering & modifying text (such as a python program) Pseudocode is an informal description of a sequence of steps for solving a problem (in normal english, read by humans) Function (programming instruction that carries out a particular task)
