Interviewer asked general question about Python: difference between Tuple and List, what is an Iterator etc. pretty general questions. Coding exercise consisted of two parts, first part I had to write a function that returns True or False if a given number is prime number. Second question was to print in snake pattern numbers, given random n number, you had to print numbers in range of 0 to n^2, each row printed opposite order. 0 1 2 5 4 3 6 7 8
