11 - what is control flow in python?
Control flow in Python refers to the order in which the statements within a program are executed. By default, Python executes statements sequentially from top to bottom. However, control flow statements allow you to alter this default order, enabling your program to make decisions, repeat actions, and execute specific blocks of code based on certain conditions.
There are three main types of control flow statements in Python:
Sequential Control Flow: This is the default execution order where statements are run one after another in the order they appear in the code.
Decision (Conditional) Control Flow: These statements allow the program to execute different blocks of code based on whether a certain condition is true or false. Key statements include:
if: Executes a block of code if a condition is true.
elif (else if): Checks an additional condition if the preceding if or elif conditions were false.
else: Executes a block of code if none of the preceding if or elif conditions were true.
