Control Flow: Making Decisions in Python

Programming is all about making decisions. Control flow tools like if statements, loops, and functions let your code respond to different situations. The if statement is the simplest decision maker. You can write if condition: do something, elif another condition: do something else, and else: do this if none match. Indentation is crucial here. Python uses indentation to know which code belongs to which condition. Loops let you repeat actions. A for loop is great for going through a list or a range of numbers. For example, for i in range(5): print(i) prints numbers 0 through 4. A while loop runs as long as a condition is true. Be careful with while loops to avoid infinite loops. You also have break to exit a loop early and continue to skip the rest of the current iteration. Learning to combine these structures allows you to solve complex problems. Try building a simple guessing game. The program picks a random number, and the user has to guess it. You will use loops to keep asking and conditionals to check if the guess is correct. This kind of project solidifies your understanding of control flow.
