Therefore, a while loop would be perfect for this scenario. We can't possibly know in advance how many times the user will enter an invalid input before the program can continue.
User Input: When we ask for user input, we need to check if the value entered is valid.These are some examples of real use cases of while loops: 💡 Tip: if the while loop condition never evaluates to False, then we will have an infinite loop, which is a loop that never stops (in theory) without external intervention. When we write a while loop, we don't explicitly define how many iterations will be completed, we only write the condition that has to be True to continue the process and False to stop it. This type of loop runs while a given condition is True and it only stops when the condition becomes False. They are used to repeat a sequence of statements an unknown number of times. Let's start with the purpose of while loops. 🔅 🔹 Purpose and Use Cases for While Loops
