Python Tutorial 13: Understanding Python While Loops

You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming:

In this video we show step-by-step instructions on how to understand and use python while loops. I do not assume you are an expert, so these lessons are designed for complete beginners.

I did watch your Ardiuno, Raspberry Pi, and little bit AI on Jetson series...
Being Electronics student everything what you are doing is helping me a lot...
Even I did my college project using your series..."Attendance system using face recognition on Raspberry yor are lifting us up..
Huge respect towards you sir
Thanks a lot....🤩

I AM FINALLY LEGEND after a losing streak! Having so much fun with these lessons.

[yousraabdullah]

Ugrades = int(input('How Many Grades You Have? '))
gradeslist = []
g = 0
p = 0
while g in range(0, Ugrades, 1):
grades = float(input("please Enter Your grades Don't Be Shy : "))
g += 1
gradeslist.append(grades)
print('')
print('You grades Are: ')
print('')
while p in range(0, Ugrades, 1):
print(gradeslist[p])
p += 1
I used another variable (p) to store and print the grades I was mad that It didn't work thou I used the increment But when I saw you work I knew my wrong.
Thanks for the Lessons Mr Paul

I am legend, despite this homework was easier than other ones.

I AM A LEGEND
I got this one correct & yeah it was a bit easy.Got to mention that your homework assignments are really helpful.
Thank you for sharing your knowledge with us

[dawidstawowy]

I'm legend. It took me 2 minutes to figure out this homework, probably because previous one took me 6 hours, but I couldn't even imagine that i'm folding up like a cheap Walmart chair!.
Thank You unce Paul for this incredible new tutorial series!

Got it, Paul, I am legend. Enjoyed the lesson. Looking forward to reading and writing files. Have a great week.

I just wanted to add, I am really enjoying these lessons, with the tools you have given so far, I wrote my own little program to collect and sort two data sets for a string input and then an associated value in no particular order until the user types exit, then it sorts the data by the value and re-orders both data sets to finally print the string against its value from highest to lowest. Of course I made mistakes but the joy of fixing these and seeing the program do what you wanted it to do is great.

Legend. I was able to do the assignment in about ten minutes once I got past the initial "...how do I make this work" brainstorming phase.

[MrElFRanz]

Hello Paul,
I completed the while homework, this one was easier than the last one, for which I needed hours. I could do the while homework in minutes. Thanks for your marvellous lessons.

I got my while loop to print the index from the beginning to the end of the array, and then print from the end back to the beginning! Counting backward requires a bit of manipulating the variables and changing the addition operator, but it was pretty simple. Another awesome lesson Paul!

GOT IT, AFTER ALMOST 2 HOURS 🤭
Tgrades=float(input('How many grades do you have? '))
H=[]
k=1
while k<=Tgrades:
grade=int(input('Please enter your grade: '))
k=k+1
H.append(grade)
print('Your grades are: ')
print(H)
f=-1
while f<Tgrades-1:
f=f+1
print(H[f])

[cbrombaugh]

I AM LEGEND! it seemed easier than the for exercises. Looking forward to catching up to current lesson. Again, thanks for the most excellent courses, Paul.

I managed to do this assignment, I was preety weary at first seeing as I orginally struggled on for loops initially however now I feel like I have a grasp on the concept before moving on to this lesson so I understood it preety easily when boiled down it is just a different way to format for loop (but in my opinion easier) one thing I did learn though (mostly from me never doing it is knowing you could re apply a variable (in this case j) mid code in my code I just made a new variable for the 2nd while loop

really enjoying this series thank you sir!

[pralaymajumdar]

Very knowledgeable and inspirational lecture... Thank you sir and waiting for the next week.

[OzdemirCem]

Paul's words are really understandable. Congratulations. Doing homework is very important. The code is not written without encountering the problem.

[sudhanshupawar]

i used to hate programming before i started watching your tutorials...you really make programming fun

[alfredcalleja]

Hi Paul, in my version of this coding I used i and j for each of the loops and set my i counter to start at 0 and the j counter to start at 1 in the appropriate parts of the code: it all worked well. Thanks for another interesting and informative tutorial.

[mohsenr]

I did the homework and debugged it on my own. Good lesson as always, thanks.

[tejkhanvilkar]

​really appreciate your video one more amazing lesson
Thanks Paul
