The throws this error,

Hi @roshin93,

Your posted code is not formatted, so it does not display properly. See Quick Tips for Writing Good Posts.

There may be a bug in the exercise page. Refresh that page, submit the code again, and be sure to enter a number at each of the two prompts.


“It” is taking input from the interface as opposed to the console - Can’t be bothered to carry on until this is fixed!

I was enjoying learning Python but am really fed up with this. The following is code I wrote

print "something"
guess_row = 0
guess_row = int(raw_input("Guess Row: "))
print guess_row
print “anything”

Which results is either the error msg quoted elsewhere or just “egg-times” for ever.


If there is/was a bug have you fixed it?


I am not in a position to fix it myself. Codecademy staff are aware of the bug, and we are looking forward to their correcting the problem.
