About this Video:
This video covers difference between a for loop and a while loop in Python using example codes and flow-chart. This video is a part of Episode 09, and is posted as a separate video here at the request of the viewer(s).

in Python, there are 2 ways to create loops if we want to re-use a block of code. We can either use a “for-loop” or a “while-loop”.

If we have a block of code that needs to be repeated a predefined number of times, then we will use a for-loop. In order words, for-loop is a finite loop that iterates for known number of times before it stops.

On the other hand, a while-loop iterates until a stop-condition is met. In other words, if we need our code to be repeated while an exit-condition has not been reached, we will use a while-loop. A typical example is a game-loop that keeps running for hours or days until user wants to terminate the game.
