Sometimes, you need your code to execute repeatedly as long as a specific condition is true. You can accomplish this using a while loop, which follows this structure:

while condition:
    # While `condition` is `True` execute this

To use a while loop effectively, start by initializing a counter variable and update it within the loop to avoid an infinite loop.

1234567
# Assign starting number (counter) i = 1 # While loop will print all the numbers to 10 while i < 10: print(i, end=' ') i = i + 1 # Increasing variable
copy

The print() function outputs each result on a new line by default. To separate outputs with a space, you can use end=' ' in the function.

The loop's logic includes the statement i = i + 1 to ensure the condition i < 10 eventually becomes False. Without it, the loop would run indefinitely.

What will happen if the line i = i + 1 is omitted from the while loop?
