Using a while loop in Python to maintain a counter and a running total

Maintaining a counter and computing a running total

[frambuella]

I'm in my first month of learning python and was having a bit of trouble getting the while loop to change my counter variable. This video was so clear, I don't think I'll forget this concept anytime soon, thanks for the help !

Thanks! I just started my full stack developer courses and I was struggling with one of the Python lab exercise. This helped me because the principle is the same here.

Thank you for the help 7.5 years after posting this. Still useful!

[artbylucentgem]

Thank you! You helped me wrap my brain around an issue I was having. You rock. :)

[mhondr]

Really clear and straightforward to understand!

Finally!! Someone that actually shows how to apply while loops in an actual scenario. I watch 20 other YouTubers use the same x=0 x+1 example which was not helpful at all so thank you for this!! 🙌🙌

Thank you for this very clear explanation it made a lot of sense. Very much appreciated

[danielbirdsall]

I enjoyed that tutorial, thank you. Very productive way to use the while loop.

[fredamills]

Awesome, thank you. You explain so well.

Thanks for this video! very clear


I still got a question

How can I make it run from the beginning witout restarting the programme?
Like starting again making a new calculation, maybe for the 2nd waiter or the next day, so i want to enter tip amounts again. How could I do that? With a loop?

[jasawnabowen]

why did you set the values equal to 0 in the beginning before the while loop?

[ryanli]

What if the waiter mistakenly enters a negative number which does not make sense? The program still runs the calculation :)

This is very helpful. I'm doing something similar to this, but I'm checking for average test scores with boys vs girls. Is there a way to increment the two in the same loop? I keep getting a syntax error for indention.

Hi Mark, i'm new to coding and i needed some help with my code. I need to create a molecular mass calculator and so far i have created variables and assigned their atomic mass. I've used a for loop and if/else statements in my code and so far it can recognise the letter and print out its atomic value one under the other. I need help to be able to add them.

[matiasconscious]
