Python for loop vs while loop Thefor loopis usually used in the sequence when the number of iterations is known. For example, # loop is iterated 4 times for i in range(4): print(i) Output 0 1 2 3 Thewhileloop is usually used when the number of iterations is unknown. For example,...
In the above example the loop is terminated when x becomes 5. Here we use break statement to terminate the while loop without completing it, therefore program control goes to outside the while - else structure and execute the next print statement. Flowchart:Previous: Python For Loop Next: Pyt...
The while Loop With thewhileloop we can execute a set of statements as long as a condition is true. ExampleGet your own Python Server Print i as long as i is less than 6: i =1 whilei <6: print(i) i +=1 Try it Yourself »...
How To Make A While Loop in Python Now that you know what you need to construct a while loop, all that is left to do now is to look at a real-life example where the while loop is used before you start making exercises on your own! Consider the following example: # Take user input...
The else Clause In While Loop Python provides unique else clause to while loop to add statements after the loop termination. This can be better understood by the following example, x =1while(x<=3):print(x) x = x +1else:print("x is now greater than 3") ...
Python does not have a built-in "do-while" loop, but you can emulate its behavior. Emulating Do-While Behavior To emulate a "do-while" loop in Python, you can use a while loop with a True condition and strategically place a break statement. Here's an example: while True: # Execute...
For example, say that you want to implement a number-guessing game. You can do this with a while loop: Python guess.py from random import randint LOW, HIGH = 1, 10 secret_number = randint(LOW, HIGH) clue = "" # Game loop while True: guess = input(f"Guess a number between {LO...
do { // body of while loop } while (true); The infinite loop is useful when we need a loop to run as long as our program runs. For example, if your program is an animation, you will need to constantly run it until it is stopped. In such cases, an infinite loop is necessary ...
The‘condition’will be the criteria based on which the loop body will be executed. Till the condition holds true, the loop body is executed. As soon as it becomes false, python will stop executing the loop body. Let us understand with the help of an example. ...
If the password isnotcorrect, thewhileloop will continue to execute. Info:To follow along with the example code in this tutorial, open a Python interactive shell on your local system by running thepython3command. Then you can copy, paste, or edit the examples by adding them after the>>>...
