Can somebody explain me for and while loops? Because I know that they are in course for python but I just don't understand them.

Well with while loops you can do the exact same as for loops, but also you can change the rate of incrementation and the stop condition. Personally, I use while loops when I don't know when I want to stop 😅😅 For example, imagine you have a function prime() and you want to print the first n prime numbers. How do you do it with a for loop ? Honestly I don't know, because we need to stop the loop somewhere and with a for loop in this case it is tricky to find the end. So we'll do this: number_primes=0 while not number_primes==n: if prime(number_primes): print(number_primes) number_primes=number_primes+1 So there's an example where you can use a while loop but can't use a for loop. I hope it helped...

I have written two detailled tutorials about what you can do with 'for' in Python. I'll have to let someone else handle while. 😉 https://code.sololearn.com/cSdiWZr4Cdp7/?ref=app https://code.sololearn.com/ck6HicJ6Z8jG/?ref=app
