[]

The built-in function len() also applies to lists:

>>> len(a)

[issue10109] itertools.product with infinite iterator cause MemoryError.

2010-10-14 Thread Jeong-Min Lee 

New submission from Jeong-Min Lee :

According to the documentation, itertools.product is equivalent to nested 
for-loops in a generator expression.
But, itertools.product(itertools.count(2010)) is not.

>>> import itertools
>>> (year for year in itertools.count(2010))
 at 0x026367D8>
>>> itertools.product(itertools.count(2010))
Traceback (most recent call last):

[issue6316] format, str.format don't work well with datetime, date object

2009-06-20 Thread Jeong-Min Lee 

New submission from Jeong-Min Lee :

format(datetime_obj, format_string) return format_string. (when
format_string is not empty.)


>>> import datetime
>>> d = datetime.datetime.now()
>>> format(d)
'2009-06-20 23:51:54.243428'
>>> format(d, '')
'2009-06-20 23:51:54.243428'
>>> d
datetime.datetime(2009, 6, 20, 23, 51, 54, 243428)
>>> '{0}'.format(d)
'2009-06-20 23:51:54.243428'
>>> '{0:30}'.format(d) # odd
'30'
>>> format(d, '30') # odd
'30'
>>> format(str(d), '30') # workaround
'2009-06-20 23:51:54.243428'
>>> '{0!s:30}'.format(d) # workaround
