  • \$\begingroup\$ 29 bytes, you don't need to cast the input to an int because the input function in Python 2 does eval on the input before returning. You also don't need parentheses around the input call. \$\endgroup\$ Commented Sep 29, 2017 at 22:02
  • \$\begingroup\$ Oh, actually... This code doesn't even work. Theoretically, it would work if infinite 1's were given as input, but that doesn't meet the spec. Since while is calling the input function every time, it will just print one 1 and then reach the end of the input and error. Your earlier solution with command line args did work, or you can assign the input to a variable before looping. \$\endgroup\$ Commented Sep 29, 2017 at 22:13
  • \$\begingroup\$ @LyricLy yeah, I tried that once. Thanks! \$\endgroup\$ Commented Sep 30, 2017 at 19:14
