Exercises (contributed solutions)

1. Study what the enumerate function does and write your own my_enumerate that has the same effect.
2. Write a generator clock_generator() which starts at midnight, moves the time by one hour and returns the time in 12-hour format, e.g. 11 am or 3 pm and we can call it and advance by one hour infinitely many times:

   >>> my_clock = clock_generator()
   >>> print(next(my_clock))
   12 am
   >>> print(next(my_clock))
   1 am
   >>> print(next(my_clock))
   2 am
   >>> print(next(my_clock))
   3 am
   

3. Write a generator which returns the next element of this infinite series: 1, 2, 3, 4, 5, 5, 4, 3, 2, 1, 1, 2, 3, 4, 5, 5, 4, …
4. Write a function which draws or prints a snowflake or x-mas tree in text or ASCII art or somehow - use your creativity! Extra points for using recursion. More extra points if the size can be given via argument.
