A control structure (or flow of control) is a block of programming that analyses variables and chooses a direction in which to go based on given parameters. In simple sentence, a control structure is just a decision that the computer makes. So, it is the basic decision-making process in programming and flow of control determines how a computer program will respond when given certain conditions and parameters.
Flow of control through any given function is implemented with three basic types of control structures:
🔷 Sequential: default mode. Sequential execution of code statements (one line after another) -- like following a recipe
🔶 Selection: used for decisions, branching -- choosing between 2 or more alternative paths. In Python, these are the types of selection statements:
◼️ if
◻️ if-else
◼️ if-elif-else
🔷 Repetition: used for looping, i.e. repeating a piece of code multiple times in a row. In Python, there are three types of loops:
◼️ while
◻️ for
