Bad example in Chapter 3 of Python 2.6.5 Tutorial
by Dylan Laufenberg 11 Jun '10

11 Jun '10

Hi there. This should be easy to fix, and I may be wrong (I'm just learning Python), but I believe the behavior of negative list (in this case, string) indices is such that a[-1] returns the *last* element, not the second-last. However, near the bottom of the Strings section of Chapter 3 of the official tutorial (link <http://docs.python.org/tutorial/introduction.html#strings>) is a section and table regarding this, conflicts with itself: the ASCII table near the very bottom lists the indices wrong! Thank you for your help, and I do apologize if I am mistaken, but I'm fairly sure I'm right. :)

Bug in documentation of os.mkdir()
by Raphael.Mankin＠rbs.com 11 Jun '10

11 Jun '10

The web page http://docs.python.org/library/os.html#file-object-creation does not specify what os.mkdir() does if the directory already exists. Makedirs() does, but mkdir() does not. *********************************************************************************** The Royal Bank of Scotland plc. Registered in Scotland No 90312.

by Charles Reinman 11 Jun '10

11 Jun '10

In the sentence: “Private” instance variables that cannot be accessed except from inside an > object, don’t exist in Python. The comma is extraneous and should be removed. http://docs.python.org/tutorial/classes.html#private-variables Thanks, - Charles

Documentation error for conditional expressions?
by Ken Shirriff 11 Jun '10

11 Jun '10

The conditional expression documentation says: conditional_expression ::= or_test ["if" or_test "else" expression] I've stared at this and the PEP, and I''m pretty sure that the first or_test should be an expression, not an or_test. In an expression like "x if C else y", x and y are expressions and C is the or_test. The documentation in question is at http://docs.python.org/reference/expressions.html#conditional-expressions Ken

Add reference
by Vo, Chanh Q 11 Jun '10

11 Jun '10

Hi In MS visual studio I use add reference to add the COM or API of drivers ... to MS visual studio. In Python what is the equivalent way to add reference? For example: I have USB GPIB card from National instrument. I installed visa and IEEE488.2 drivers that have GPIB driver. Now in Python, how do I used function built in visa or IEEE488.2 to write read instrument that runs on GPIB? Thanks Chanh

[issue8939] Use C type names (PyUnicode etc; ) in the C API docs
by STINNER Victor 11 Jun '10

11 Jun '10

STINNER Victor <victor.stinner(a)haypocalc.com> added the comment: "PyUnicodeObject*" is not the best choice for the description of the function, and I don't really like "PyUnicode". Can't we use C types in the function prototype and Python types in the description? Example: ------- s (PyUnicodeObject* or None) [char *] Convert a null-terminated C string to a Python unicode object using 'utf-8' encoding. If the C string pointer is NULL, None is used. ----- PyUnicodeObject will be a link to the C type, and unicode a link to the Python type. ---------- _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue8939> _______________________________________

Mark Dickinson <dickinsm(a)gmail.com> added the comment: FWIW, I prefer PyLongObject* over PyLong. (Though I'm sure I'm guilty of writing PyLong in comments.) ---------- nosy: +mark.dickinson _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue8939> _______________________________________
