[issue28306] incorrect output "int division or modulo by zero" in Handling Exceptions tutorial

2016-09-28 Thread Viorel Tabara 

New submission from Viorel Tabara:

I'm reading the Python 3.5.2 documentation at:
  
   https://docs.python.org/3/tutorial/errors.html#handling-exceptions

which shows the following example:

   >>> def this_fails():
   ... x = 1/0
   ...
   >>> try:
   ... this_fails()
   ... except ZeroDivisionError as err:
   ... print('Handling run-time error:', err)
   ...
   Handling run-time error: int division or modulo by zero 

Running the code as a script produces:

   $ python3 -V
   Python 3.5.2
   $ python3 p.py
   Handling run-time error: division by zero

   $ python2 -V
   Python 2.7.12
   $ python2 p.py
   ('Handling run-time error:', ZeroDivisionError('integer division or modulo 
by zero',))
   
The same output is listed for 3.6 and 3.7 tutorials but I don't have those 
versions installed on my system.

[issue28315] incorrect "in ?" output in 'divide' example at "Defining Clean-up Actions" in tutorial

2016-09-29 Thread Viorel Tabara 

New submission from Viorel Tabara:

At https://docs.python.org/3.5/tutorial/errors.html#defining-clean-up-actions 
when I'm running the "divide('2', '1')" example I get:

  File "", line 1, in 

instead of the documentation output of:

   File "", line 1, in ? 

The same message is included with the 2.7 tutorial.

To wit:

Nice tutorial by the way ;) Thanks!

[issue28677] difficult to parse sentence structure in "When an instance attribute is referenced that isn't a data attribute"

2016-11-12 Thread Viorel Tabara 

New submission from Viorel Tabara:

Method objects are explained at:

https://docs.python.org/3/tutorial/classes.html#method-objects

I'd like to suggest a change from:

   When an instance attribute is referenced that isn’t a data attribute, its 
   class is searched. 

to something along this line:

   When an instance attribute --- that isn’t a data attribute --- is 
   referenced, the instance parent class will be searched.

David, that sounds clear enough to me, thanks. However, English isn't my first 
language so I can't comment on the grammatical subtleties.
