Using Advanced while Loop Syntax The break Statement: Exiting a Loop Early The continue Statement: Skipping Tasks in an Iteration The else Clause: Running Tasks at Natural Loop Termination Writing Effective while Loops in Python Running Tasks Based on a Condition With while Loops Using while Loops...
whileloops are often used with a counter — an incrementing (or decrementing) number. Like this: counter=1 while(counter<10): print(counter) counter=counter+1 Result 1 2 3 4 5 6 7 8 9 Here's what the program is doing: Set a counter to1 ...
In the last post aboutPython "for" loops, we got introduced to Python's concept and how does Python handle loop. With different variations and methods introduced in loops, we are all set to move ahead to the next and probably the only other important loop in Python:python while loop. Sin...
2while loopExecutes a block of statements repeatedly as long as the condition is TRUE. These two types of loops can be used inside each other to generatenested loops(more on this later). General Use Of Python Loops In Python, loops can be used to solve awesome and complex problems. You ...

The iterator i is set to zero at the start of the loop and continues to increment each cycle. The loop continues to run while i is less than 5. The code block prints out the new value of the iterator each time it runs. File: loop1.py 1 2 3 for i in range(5): print("The...

Two basic loop types are for loops and while loops. For loops iterate through a list and while loops run until a condition is met or until we break out of the loop. We used a for loop in earlier scripts (e.g., pass.py), but we haven't seen a while loop yet:...
