Python: While Loops (Reading User Input Indefinitely?!!)

In this video in the Python tutorial for beginners, I am going to teach you all you need to know about While Loops in Python by going through an example where a user has to interactively enter multiple numbers indefinitely, and we only stop when the input is a negative number.
I will discuss why we need while loops in programming, and the difference between For loops and While loops.

This guy is a great teacher! I'm taking Programming Logic through college and it is confusing. After watching this Afternerd I get it!

This is a great explanation, but I think adding the sum function makes it more confusing than it needs to be. It took me a while to understand this video to be honest. Maybe a better example would be something like: i = True while i == True: answer = input("Do you want to continue?" if answer == "Yes" : i = False print("End of loop") Please excuse any mistakes or weird formatting, I am very new to programming.

sum=0 num = 0 while num >=0: num=int(input("Enter a positive integer: ")) if num >=0: sum +=num print(f"sum is {sum}") Sorry because i just started this, but doesnt this look more optimized than your code? Sorry for asking.
