[issue1982] Feature: extend strftime to accept milliseconds

2008-01-31 Thread Andreas Balogh 

New submission from Andreas Balogh:

Currently serializing datetime objects into isoformat string is well
possible. The reverse process - parsing an isoformat string into a
datetime object - doesn't work due to the missing %-tag for the strftime
format string.

Proposal:
Add new tag to strftime like format strings allowing to print and parse
milliseconds.

[issue1982] Feature: extend strftime to accept milliseconds

2008-11-17 Thread Andreas Balogh 

Andreas Balogh <[EMAIL PROTECTED]> added the comment:

Yes, microsecond support is fine. Elaborating on my initial comment.

The following should assert:

a_datetime = datetime.now()
a_datetime.replace(microsecond = 1)

iso_str = adatetime.isoformat()
b_datetime = datetime.strptime(iso_str, "%Y%m%dT%H%M%S.%f")

assert(a_datetime = b_datetime)

The datetime shall be an invariant. 

Fixed from my point of view, Andreas

Some typos corrected. Sorry for any inconvenience.

a_datetime = datetime.now()
a_datetime.replace(microsecond = 1)

iso_str = a_datetime.isoformat()
b_datetime = datetime.strptime(iso_str, "%Y-%m-%dT%H:%M:%S.%f")

assert(a_datetime = b_datetime)

- a_datetime.replace(microsecond = 1)
+ a_datetime = a_datetime.replace(microsecond = 1)

Thanks for spotting the bug.

[issue7198] csv.writer

Andreas Balogh  added the comment:

I encountered the same problem. It is unclear that using binary mode for the 
file is solving the problem. I suggest to add a hint to the documentation.
