We can use abreak statementinside awhileloop to terminate the loop immediately without checking the test condition. For example, while True: user_input = input('Enter your name: ') # terminate the loop when user enters end if user_input == 'end': print(f'The loop is ended') break pr...
Sometimes we want a part of the code to keep running, again and again, until we are ready for it to stop. Let’s see how while loops can help us do this! Python While 1 Run the example: In this code, we import time so we can use a “wait” function called sleep() . Then, ...
For example the following code never prints out anything since before executing the condition evaluates to false. x = 10; while (x < 5): print(x) x += 1 CopyFlowchart: The following while loop is an infinite loop, using True as the condition:x = 10; while (True): print(x) x +...
Let's revisit the very first while loop example once again to determine what now exactly are the differences between while and for loops. You already read above that the difference lies in the condition that is or is not involved, but how does this reflect in the code and how can you ma...
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...
For example, if n is 5, the return value should be 120 because 1*2*3*4*5 is 120. 1 2 def factorial(n): Check Code Video: Python for Loop Previous Tutorial: Python if...else Statement Next Tutorial: Python while Loop Share on: Did you find this article helpful?Our...
print(f"This is loop number {count + 1}") 在上述代码中,使用了for循环,遍历范围为range(max_count),即从0到max_count-1。在每次循环中,打印当前循环次数。这样可以实现与计数器变量相同的效果。 三、使用break语句 还有一种方法是使用break语句,在while循环中手动控制循环次数。通过在循环体中判断计数器是否...
for loop inside While loop When To Use a Nested Loop in Python? What is a Nested Loop in Python? A nested loop is a loop inside the body of the outer loop. The inner or outer loop can be any type, such as awhile looporfor loop. For example, the outerforloop can contain awhile...
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 your code here if not condition: break Powered By In this structure, the loop executes...
Example of while Loop in Python Here is the example code that uses the while Loop in Python. Python count =0 whilecount<5: print(count) count +=1 Output: 0 1 2 3 4 Explanation: Here, the while loop repeats the code block until the count variable is less than 5. During each iterat...
