While not Python | Example code

  • by

While not loop works the same as a simple while loop, it will repeatedly execute the loop’s body until the condition for loop termination is matched. Where a boolean expression executes the loop’s body if the condition evaluates to False.

count= 3

while not (count== 0) :


   count= count- 1

As the above code loop will execute until the count is zero.


While not Python

While not a Python example with an iterable object

The above example code only used a single variable. Let’s execute the loop’s body if the variable is not present in the iterable object.

a_list = [1, 2, 3]

while 3 not in a_list:
    a_list.append(len(a_list) + 1)


Output: [1, 2, 3]
