Hi all, I've found the tutorial [1] to be a great resource to start using Python effectively. So in the spirit of leaving the campsite cleaner than you found it I post a few issues that caught my eye. Every issue is prefixed with the number of the tutorial section it pertains to. 5.1 `del` is referenced in description of `list.clear()` before being introduced in section 5.2. 6.3 `dir` prints more names for fibo, output on 3.7.3: >>> dir(fibo) ['__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__', 'fib', 'fib2'] 10.4 Actual output includes the number of bytes written (47), which is omitted in the sample output 10.7 The sample URL (http://tycho.usno.navy.mil/cgi-bin/timer.pl) is inaccessible - the sample does not work. 16.1.1 "cause an exit with a nonzero exit" - is "status" missing at the end?
