Answer 1

def alphapat(n):

num = 65

for i in range(0, n):

for j in range(0, i+1):
ch = chr ( num )
print(ch , end=" ")
num = num + 1 #inside inner loop.

print("\r")

n = 5
alphapat(n)

Answer 2

Bob_Li '\r' is a carriage return escape character it works differently on different operating system.
On linux it works like backspace but on windows it works similar to '\n' i.e. new line character

Answer 3

Jayakrishna🇮🇳
cool code😎
I never understood what print('\r') does, though. print() seems to work ok.
Btw, did Sololearn add a codeblocker in the reply form? I get this no connection message and cannot submit when my reply contains code...
But you obviously can do it.
very strange.🤔
and if I copy paste your code, i can submit it.
even stranger.😲😲
Anyway, I made some modification in your code to keep the range in the capital letters if n is large.

Answer 5

Bob_Li
As @Snehil said, '\r' is carriage return works depends on operating system. Here it won't work. Am not added it. OP trying it in System. So it it works there.. I just edited code to work it properly as expected output.

Also yes, I faced same trouble and find that chr function is blocking to add code so added a space=> chr () . Reason I don't know, I already asked Sololearn staff and other senior mentors and waiting for their response.

Answer 6

❓❓chr ()❓❓
or
gvhgvvbhvbvg chr ()hhbvgcv

Jayakrishna🇮🇳 you are right. remove the space between 'chr (' and it blocks.
also the chr must have a space before it.

Answer 7

Bob_Li Yes. Trying without a space between, it's blocking.

Answer 8

Add num += 1 inside inner loop. Not after..

Answer 9

Answer 10
