[SOLVED] need help with a problem in python

Question

I try to print the following:

123
456
789

or at least:

1
2
3

4
...

My code:

i=1
while i <= 9:
print(i)
i = i+1
if i % 3 == 0:
print("\n")

Output:

1
2

3
4
5

6
7
8

9

How can I print this in 3 similar blocks?

Thanks

Answer 1

You are almost there.
Instead of updating i first and check for %3, you should switch the two statements so it checks the current plotted i

print(i)
if i%3 == 0:
print("\n")
i=i+1

You could also use a nested loop and the end property of the print function:

while i <= 9:
for a in range(3):
print(i,end="")
i=i+1
print()

Answer 2

You're on the right path, just a rearrangement would do the trick:

i = 1
while i <= 9:
print(i, end="")
if i % 3 == 0:
print()
i = i+1

Answer 3

i=1
while i<=9:
print(i,end="")
i=i+1
if (i-1)%3==0:
print()

Answer 4

wow, that was quick. Many thanks for your help.

Michael, as your problem is solved, it will be very kind of you if you can
(i) Mark best answer, and
(ii) edit your question title to begin with a [SOLVED] so the other sololearners won't need to pump in?

Answer 6

Thank you, Michael.
Further to the above solutions, may I supply two examples for your as enrichment:
The first one is how you can do this without the end property of print function :
