Confusion in os.path documentation
by Reuben Thomas Dec. 14, 2011

Dec. 14, 2011

In the following, from the os.path documentation, the second sentence sounds like it’s referring to a consequence of the first, but it’s not: normalizing paths containing symbolic links can change their meaning: "On Windows, it converts forward slashes to backward slashes. It should be understood that this may change the meaning of the path if it contains symbolic links!" Hence, I suggest the following rewrite: "On Windows, it converts forward slashes to backward slashes. Note that normpath() … [View More]

[issue13549] Incorrect nested list comprehension documentation
by Matt Long Dec. 13, 2011

Dec. 13, 2011

New submission from Matt Long <matt(a)crocodoc.com>: The description of nesting list comprehensions in section 5.1.5 of the main Python tutorial (http://docs.python.org/tutorial/datastructures.html#nested-list-comprehensi…) is misleading at best and arguably incorrect. Where it says "To avoid apprehension when nesting list comprehensions, read from right to left." This is incorrect and conflicts directly with the comment at the bottom of PEP 202 (http://www.python.org/dev/peps/pep-0202/),… [View More]

Misleading yield as a statement vs an expression
by Amirouche Boubekki Dec. 12, 2011

Dec. 12, 2011

Héllo, Documentation about the yield *expression* can be found twice at [1] and [2]. This is misleading, I think only the [2] is relevant since PEP 342 [3]. HTH, [1] http://docs.python.org/reference/expressions.html#grammar-token-yield_atom [2] http://docs.python.org/reference/simple_stmts.html#grammar-token-yield_stmt [3] http://www.python.org/dev/peps/pep-0342/
