Python while Loop In Python, we use awhileloop to repeat a block of code until a certain condition is met. For example, number = 1 while number <= 3: print(number) number = number + 1 Output 1 2 3 In the above example, we have used awhileloop to print the numbers from1to3. ...
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") ...
In this example, when the loop finds that number isn’t greater than 0, it immediately terminates the execution without entering the loop body. So, the body never executes.Now that you know the basic syntax of while loops, it’s time to dive into some practical examples in Python. In ...
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 » Note:remember to increment i, or else the loop will continue forever. Thewhileloop requires relevant variables to be ready, in this example we need to def...
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...
Python While 1 Run the example: In this code, we import time so we can use a “wait” function called sleep() . Then, we make a new variable called alive and set it to True. When you make a variable equal to True or False, you are making abooleanvariable. This means it can onl...
The basic loop structure in Python is while loop. Here is the syntax.Syntax:while (expression) : statement_1 statement_2 ...The while loop runs as long as the expression (condition) evaluates to True and execute the program block. The condition is checked every time at the beginning of...
An example of an infinite loop: while 1==1: print("In the loop") This program would indefinitely print "In the loop". You can stop the program's execution by using the Ctrl-C shortcut or by closing the program. 无限循环是一种特殊的while循环;它从不停止运行。它的条件总是正确的。

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. ...
