Applied Computational Thinking with Python
By :
Simply defined, control flow is the order in which an algorithm reads and executes instructions, functions, and statements. Control flow means the computer will make a decision. Think about it this way: when I go outside my building, I'll either use an umbrella or I won't use an umbrella. That depends on whether or not it is raining (and whether or not I remembered my umbrella, I guess). Depending on that condition, we make a decision. That process is the control flow process in algorithm design.
Let's look at some of the control flow statements available in the Python programming language:
