 Dive into python seems to be quite popular  can be read online fro free



Learning Python by Mark Lutz, from O'Reilly is a good one, I've been
reading it and it also enforces a comparison between C programming and
Python. However, it's focused on Python 2, but it also mentions Python
3 things in the text...

 There is a new edition out, copyright 2010 if I recall correctly, that
 updates its coverage to Python 3.x, which is the book's primary focus,
 though it points out where 3.x syntax does not work in version 2.x.

Oh thanks! that I didn't knew...

strptime format string nasty default

2012-05-09 Thread Javier Novoa C. 
Hi,

I am using time.strptime method as follows:

I receive an input string, representing some date in the following
format:

%d%m%Y

However, the day part may be a single digit or two, depending on
magnitude.

For example:

'10052012' will be parsed as day 10, month 5, year 2012

Again:

'8052012' will be parsed as day 8, month 5, year 2012

What happens when day is 1 or 2?

'1052012' will be parsed as day 10, month 5, year 2012 

That's not the expected behaviour! Not for me at least. I mean, in my
case, month will always be a 2 digit string, so there's no ambiguity
problem by pretending that... say '1052012' is correctly parsed.

Is there a way out of here? I know I can pre-parse the string and
append a '0' to it when lenght == 7, but I think that a better way
would be if strptime allowed me to define my format in a better
way... To say that the month is the optional one-two digit part is
just a default, isn't it? Why can't I specify that the day part is the
one with one-or-two digits on the input string...?

Or is there a way out that I don't know yet?

 You'd have to read the strptime(3) manual page (it's a Unix function,
 imported straight into Python, I'm sure). Judging from a quick read
 it's not intended to support things like these. I'm surprised it
 doesn't parse your last example to (10, 52, 12) and then fail it due
 to month12.

Well, it doesn't, at least on my Python. I'm using 2.7.3 version


 Can't you use a standard date format, like ISO? Apart from not being
 possible to parse with standard functions, this one looks quite odd
 and isn't very human-readable.

No, sadly the input doesn't depends on me :-(


 If you have to use this format, I strongly recommend parsing it
 manually as text first. Then you can create an ISO date and feed
 that to strptime, or perhaps use your parsed (day, month, year) tuple
 directly.

Ok, I'll do that.

Thanks!
