Answer 1

You are actually very close. There are multiple ways you can achieve this, but I guess you want to do it strictly only via loops?
no_rows=3 # number of rows
for row in range(no_rows):
for one in range(row):
print("0",end="")
print("1",end="")
for i in range(no_rows-1-row):
print("0",end="")
print()

Hatsy Rei Thank you so much sir! ☺️
I don't know why I struggle to build logic.. 😢

Answer 3

Hatsy Rei
please explain how you think about the logic to use range(no_rows-1-row)
how to visualize it?
how to think like that?
how can I think that I need to minus rows value from no_rows and -1.
how sir how? 😑
in future I want solve my problems myself.. please guide me.

Answer 4

How about this one? :-
no_rows = int(input() or 3)
num = 10 ** (no_rows - 1)
for i in range(no_rows):
print(str(num).zfill(no_rows))
num //= 10

Ratnapal Shende
no_rows=3 # number of rows
for row in range(no_rows):
for one in range(no_rows):
if row==one:
print("1",end="")
else:
print("0",end="")
print()
