The reason why you are getting *Runtime Error* is because you used Formatted string literals which is new in version 3.6
However, code jam used version 3.5.3 (see FAQ: https://codingcompetitions.withgoogle.com/codejam/faq Section *Platform*) *Python 3:* *3.5.3 (package: python3.5)* * numpy 1.16.2 (pip install numpy)* * scipy 1.2.1 (pip install scipy)* * python3.5 Solution.py* I believe your local python version is v3.6 or above, so you are not seeing this problem running locally. Since code jam use version 3.5.3, I suggest you switch to v3.5.3 when setting up your local env ( https://www.python.org/downloads/release/python-353/) Or avoid using any new features that were introduced later than 3.5.3. Change the printing line to *print('Case #{0}: {1}'.format(k, decrypt(n)))* would let you pass sample but still get Runtime Error in the visible test due to some bug in your code. -- You received this message because you are subscribed to the Google Groups "Google Code Jam" group.
