I've been working on this class assignment for my coding class for 2 days, should've taken no more than 15 minutes. Couldn't get the code to output the way expected. Your video basically helped me finally connect the dots on how to complete the assignment! Thank you!
I was struggling with nested for loops, the range function and pattern printing until this video. I've watched several videos and this was the ah ha moment. Thanks.
Awesome video. This really helped me learn nested loops. For anyone wondering how to print this triangle without using nested loops, here’s one approach: i=8 for j in range(1,17,2): print(i*" "+j*"*") i=i-1 # i is the number of spaces, and j is the number of stars being printed, which goes down by 2 each row.
why does nested for loop iterates 7 times? outside for loops iterates 7 times * nested range but why nested loop should do it 7 times too? should not it loop only 1 time as an independent loop would do?
Thank you for the great explanation , this really helped me intepret another project that was using different symbols. defintely gonna practise the pyramid for fun though.
Great vid! I got this in 4 tries, but my code was a little cleaner just because I used a variable ('x') for the number of 0s printed: x = 1 # number of 0s for i in range(0,7): # number of rows for j in range(0,7-i): # number of spaces over, starting with 7 but decreasing by 1 each time print(' ', end = '') print('0' * x) # number of zeros to print on each line x += 2 # increment the number of zeros by 2 to get increasing, consecutive odd numbers for each row (1,3,5,...)
@ in the pattern we left spaces then print 0.. it means after 7 spaces we have to print 0..then on the next line we have left 5 spaces then print 0.. likewise it goes on .. and because we have to print 2 more 0's on each next line thats why we multiply by 2 and decrease it by 1..
for i in range(0, 7): for j in range(0, 7-i): print(" ", end="") for k in range(i*2): print("0",end="") print("0") This worked for me. One thing I don't understand here, when I look at this on PythonTutor, is why in the k-index, on the first line (where i=0, and thus k=0 as 0*2=0), the program doesn't start the k loop, but instead jumps down to the print statement and then starts again at i=1. While this program accomplishes what I want, I don't understand what is going on. Since indexes start at 0, as for example in our for-loops, where the range starts at 0, allowing n to be what we want (since range goes up to n-1, if we start at 0, range will go to n), I wonder why, when i=0, k should also be 0, and then the print statement under k's loop should be printed? When following along in PythonTutor, k doesn't start until we get to the next line, with i=1 (so k's range is 1*2 = 2, so index of 0 and 1). So why does Python(?) require that i be a non-zero value, for a loop whose range is i*some-number? I just don't understand this, and any clarification from some knowing person would be amazing.
Okay, I like to try before I watch the solution. I didn't really get the isosceles triangle you got, but I did make right triangle. I just need to work on the spaces, But I don't have time right now, so heres my code so far. z,x,w,v = "*" , 1 , " ", 6 for i in range(0,4): for j in range(0,5): print(v*w+z*x) x+=1
##'QUESTION HERE## for i in range(0,7): for j in range(7 - i) /// but yours starts at (0,7): print(' ', end = '') print('0') '' why is this code giving me the same output as yours? For me its logical that second loop starts at 7 so it prints 7 spaces at start of the first iteration.
@@RecursiveTriforce How would you resolve this code to execute range values higher than 8? I am learning, and when I use your code I see that numbers 9 and above do not make perfect pyramids, so I asked myself well what should you do to fix that and make it perfect. But my problem is I barely understand your code. On top of answering this question, if you would, can you point me to some good learning websites? How did you learn this so well?

excellent explanation, I learned a lot as you went thru this step by step. Thank you.
Excellent, Sir. I really liked your approach. It is unique and most logical. I can connect the dots after every steps .
I had doubts for months about the shit for loop, I wish I watched this tutorial on my first programming day. Thank you bro

I have been to so many videos for understanding loops by far u are the best one . thanks pls keep up the good work I subscribed
You taught us this in the best possible way
Very clean and neat presentation.. Its really very helpful..
Keep up the Good Work Mate! Understood the concept...Thanks!
it was a nice, simple, and quick explanation, i understood it very quickly
iv been trying to solve this for a day. Thank you so much
You are my savior!!
Clear and objective. Really good video, thank you man, it helped a lot! Liked and subscribed!!
Thank you very much, I was able to learn this subject better thanks to your help.
why does nested for loop iterates 7 times? outside for loops iterates 7 times * nested range but why nested loop should do it 7 times too? should not it loop only 1 time as an independent loop would do?
those 2 for loops at the same indentation - think its possible to do that in a list comp?
what a nice/clear way to teach. ty
This was beautiful. thanks.

thanks for this! loved it
where are these exercises you speak of?
Super sir your video are helpful for my online classes
if you had a list of numbers how could you group every set of 4 numbers together? so if you had 12 numbers you would have 3 lists of 4.
very clean

How did you comment the piramide all at once? Seems like a usefull hotkey.
i can't figure it out too. there is a command key for commenting blocks of code at ones. i just don't understand it.

Why 8-i

Amazing! Thank you!
Will you please tell me what mathematics involved in printing pyramid. Will explain how it works?
In my program print(" ",end="") is not running.it say end="" syntax error .please give me a suggestion to solve this problem
becaus you have 2 pythone vershion!
That was awesome 😎
but how it internally implement the iteration protocol is the real magic. how does it implement it??
for i in range(6):
for j in range(0,6-i):
print(' ',end="")
for k in range(0,2*i):
print('0',end="")
print("0")
Thank u

''
why is this code giving me the same output as yours? For me its logical that second loop starts at 7 so it prints 7 spaces at start of the first iteration.
okay i got it. I forgot that the outer loop iterates only once, and the inner one iterates to the end of the range it haves. xD
try this way:
for x in range(1,10):
print(' '*(9-x)+'*'*(x*2))
for x in range(6):
print( " "*(7-x) + "0"*(2*x+1) )
In this exact problem.

way more easier tbh
when u put "for j in range(-1,17,2)" its going to add 2 to -1 until it reaches 17, right???
