[issue18177] Typo in Documents

[icedream91]

New submission from icedream91:

In library.pdf file(Release 3.3.2, June 09, 2013), I found a typo in page 149: 
I think the quotation marks are wrong in "datetime.isoformat(sep=’T’)" 
sentence, they should both be "'".
But it's right in online documents 
(http://docs.python.org/3/library/datetime.html#datetime.datetime.isoformat).

Thanks.

[issue18252] timeit makes code run faster?

[icedream91]

New submission from icedream91:

I used Python 3.3.2 to try this problem: http://projecteuler.net/problem=23 , 
and I got a correct answer.

When I wanted to check how long it took, I found something strange:
When I ran 23.py directly, it showed that it took about 13s. But if I use 
timeit module, it showed that it only took about 9s! I have tried these for 
some times, in both Ubuntu 12.10 and Windows 8, I don't understand why timeit 
will make the same code run faster.


Thanks.

I did some tests, Richard Oudkerk (sbt) is right. Thanks a lot.

[issue18326] Not Clear Docs

[icedream91]

New submission from icedream91:

I think the documents talking about list.sort() in page 
http://docs.python.org/3/library/stdtypes.html#list.sort is not clear enough. 
What asterisk means in "sort(*, key=None, reverse=None)", may be cmp argument 
from Python 2, or anything else? Or it is a typo?

I think document should explain what this asterisk means.

Thanks.

[issue18518] timeit bug?

[icedream91]

New submission from icedream91:

When I ran code below, it printed -1. The question is, the code in variable 
snippet, has wrong syntax, it can't be run. I think timeit should return only 
non-negative float type.


from timeit import timeit

snippet="""
for i in range(10):
return -1
"""

print(timeit(snippet))


Thanks.

[issue18800] Document Fraction's numerator and denominator properties

[icedream91]

New submission from icedream91:

The document (http://docs.python.org/3/library/fractions.html) doesn't mention 
Fraction's numerator and denominator properties, I knew these properties from 
dir().

Since sometimes these two properties are very useful, for example: 
http://projecteuler.net/problem=33 and http://projecteuler.net/problem=57 , I 
think document should mention them. 

Thanks.
