Printing the output tab separated..

Question

I have a program where my ouput should be tab separated.ie The function should take one parameter that represents the number of 'steps' to print. It should then return a string that, when printed, shows output like
the following:
#print(steps(3))
111
222
333
#print(steps(6))
111
222
333
444
555
666

THis is the code I have written:

def steps(no_steps):
j = 0
for i in range(1, no_steps+1):
print(("\t" * j) + (str(i) * 3) + "\n")
j+=1
return ''

print(steps(3))
print(steps(6))

BUt the output shows error as follow,

We tested your code with num_steps = 3. We expected steps to return the str
"111
222
333
". However, it returned the str "".

Please help, thanks.

Answer 1

check your steps function its returning empty string "

something like this?
def steps(no_steps):
st = ''
j = 0
for i in range(0, no_steps):
st += (("\t" * 2*(i+j)) + (str(i+1) * 3) + '\n')
j+=1
return st

print(steps(3))
print(steps(6))
