why below code run error at last line on sololearn’s code place?

Question

for i in range(1,10):
for j in range(1,10):
for k in range(1,10):
print i,j,k

Answer 1

Sololearn runs on Python 3.x syntax, where print is a function, not a statement anymore (like it is in Python 2.x).
You should go with:
print (i, j, k)

Answer 2

um... the error tells you what's wrong: you're missing parentheses.
print(i,j,k) will do the job.

Answer 3

you are missing the brackets around the print statement
plus you may be exceeding the time limit
