Did you mean to imply that it took too long?

It is likely that the terminal (emulation) is to blame, and not the python 
interpreter:

$ time python3 -c 'for i in range(10**6): print(i)' > /dev/null

real    0m1.562s
user    0m1.525s
sys     0m0.033s

Under 2 seconds on quite old hardware. Without redirection in Konsole (KDE's 
terminal emulator):

$ time python3 -c 'for i in range(10**6): print(i)'
[...]
999997
999998
999999

real    0m16.167s
user    0m5.258s
sys     0m5.512s

But wait -- you ran the code in IDLE, right?
Then book it under lessons learned ;)
