6.8 Enumerate all primes to n - bug in Python solution

**robc** · October 16, 2017, 2:43am

The basic solution has an off-by-one error. The outer loop should be for p in range(2, n + 1). Otherwise inputting a prime number to the function would exclude it from the output, which isn’t the behavior described by the comment at the top of the function (“up to and including n”) nor does it match the behavior of the improved function.
