Python Loops Tutorial

Break/Continue in a while Loop

Now, we'll attempt the same task we previously accomplished with the for loop—finding a number in the list and terminating the loop once it's located.

Examine the code below:


              12345678910
            
numbers = [2, 3, 4, 11, 5]
i = 0

# Breaking the loop, if 11 is found
while i < len(numbers):
  if numbers[i] == 11:
    print('11 is here!')
    break
  else:
    i = i + 1

How does the code work?

Great!

Please be aware that the continue statement skips a block of code within the loop for the current iteration only. Now, let's count the occurrences of 11s in the code using continue.

Examine the code below:


              123456789101112131415
            
numbers = [2, 11, 4, 11, 5]
i = -1
counter = 0

# Count all 11 in the list
# We are using len(numbers) - 1 to break the loop without being 'out of range'
while i < len(numbers) - 1:
  i = i + 1
  if numbers[i] != 11:
    continue
  else:
    print('11 is here!')
    counter += 1

print("Total number of '11': ", counter)

How does the code work?

Tarefa

Halt the loop when encountering a negative value.

Initialize a while loop, employing i to interact with numbers.
Increment the value of i.
Display a message along with the negative element.
Employ break and continue as needed.
