Python nested loops ➿

python nested loops tutorial example explained

#python #nested #loops

# nested loops = The "inner loop" will finish all of it's iterations before
# finishing one iteration of the "outer loop"

rows = int(input("How many rows?: "))
columns = int(input("How many columns?: "))
symbol = input("Enter a symbol to use: ")

for i in range(rows):
for j in range(columns):
print(symbol, end="")
print()

I found this a bit tricky to understand but think Im now there. Ive added comments to try help other people, but I'm also willing to accept I might be wrong.

# nested loop = is the general concept of having one loop inside another loop.
# nested loop = the 'inner loop' will finish all of its iterations before finishing the iteration of the 'outer loop'
# To best demonstrate this we will create a program to draw a rectangle made out of a symbol of our choice.
# We need to set a width, height and the symbol of choice.

rows = int(input("How many rows?: "))
columns = int(input("How many Columns: "))
symbol = input('What symbol would you like to use?: ')

# Now it's time for the nested loop. We're going to create an outer for loop and an inner for loop.
# The outer for loop will be in charge of the rows and the inner the columns.
for i in range(rows):
for j in range(columns): # This loop will be iterated first.
print(symbol, end="") # This will print the symbol once every iteration. Will iterate 'columns' times.
# After we use a print statement the console will start a new line. We don't want this when defining the columns so we add "end=".
print() # This will print the symbol once every iteration. Will iterate 'rows' times.
# We do want a new line when defining rows. So we add a print statement that is empty to initiate a new row per iteration.

by far the most confusing one, might have to look up the docs on this ngl

Your videos lectures are sincerely good and very easy to understand. You made me love learning Python! My two thumbs up for you Bro! Keep it up! Thank you very much!

Finally!
After practicing and Watching over and over.

Started programming for about 2 years ago and kind of lost the spark due to boring material. Decided to really do this now and must say that the content of your videos are easy to understand and inspiring!

[LittleMew]

Quick and straight to the point. Thanks!

[varunwind]

Great easy to follow tutorials. 👍🏻👍🏻👍🏻

2 lines code(god command lines) was amazing, it helped me a lot, tks Bro

how does writing print() with nothing in the parenthesis work? also typing end after print is a new one on me too. Do we always writing it = "" like that? what would happen if we put something in the quotes?

This video helped me with homework on zybook. Thank you!!!!

[cykachu]

for i in range(row):
print(sym*col)

[nope]

It finally makes some sense to me thanks keep it up

[thegamer]

alternative code :
rows=int(input("HOE MANY ROWS DO YOU WANT :"))
columns=int(input("HOW MANY COLUMNS DO YOU WANT"))
symbol=input("enter your symbol u need :")
A=symbol*columns
for i in range(rows):
print(A)

[ClickDecision]

actually this whole code is confusing to me lol. can you break it down for me step by step as to how this is working?

[quochuyluong]

I really wonder what does print() with nothing inside mean ?

[LeTrungKiena-xcfn]

Hmmm, I don't understand the last line print()

[lightheartedsiegward]

can someone tell me what is the function of the 'print()' i could'nt understand the reason behind it
