You can observe that initially ‘i’ value is initialized to 0 i.e equal to the start parameter value and stop parameter value is equal to increment value inside the while loop. 3. Conclusion We have seen how to use the Python range() in the while loop by considering three different sce...
We can simply use Python For loop with the range() function as shown in the example below. Python 1 2 3 for i in range(2,10): print(i) Output: 2 3 4 5 6 7 8 9 By default, the increment in the range() function when used with loops is set to 1; however, we can change...

is True,the indented block of codes will be executed and the loop will continue its iteration. The indented block of codes prints out the count and then increment the count by 1. Then it loops back to check for the while condition again. Once the condition becomes False, the loop ends....
