strptime and microseconds

[mathieu]

Hi there,

I am trying to use strptime to parse my microseconds but I was not
able the documentation for it. The only list I found was:

http://docs.python.org/lib/module-time.html

So I can get seconds with %S, but nowhere is there a microsecond
symbol...

Thanks for pointer to doc,
-Mathieu


s1 = "20070619"
s2 = "150348.62"
s = s1+s2
d = datetime(*strptime(s, "%Y%m%d%H%M%S.%?"))

s1 = "20070619"
s2 = "150348.62"
s = s1+s2
d = datetime(*strptime(s, "%Y%m%d%H%M%S.%?"))

Getting closer...

s1 = "20070619"
s2 = "115344.51"
s3 = "115445.123456"

ms2 = eval(s2) % 1
mms2 = int(ms2 * 1000000 + 0.5)
ms3 = eval(s3) % 1
mms3 = int(ms3 * 1000000 + 0.5)

s = s1 + s2
d1 = datetime(*strptime(s[:12], "%Y%m%d%H%M%S")[0:6])
d1.replace(microsecond = mms2)
#print d1.microsecond

s = s1 + s3
d2 = datetime(*strptime(s[:12], "%Y%m%d%H%M%S")[0:6])
d2.replace(microsecond = mms3)
#print d2.microsecond

d = d2 - d1
print d.seconds
print d.microseconds

why would d.microseconds be 0 ??

Thanks,

D'oh !

Ok final version is simply:

s1 = "20070619"
s2 = "115344.51"
s3 = "115446.123456"

ms2 = eval(s2) % 1
mms2 = int(ms2 * 1000000 + 0.5)
ms3 = eval(s3) % 1
mms3 = int(ms3 * 1000000 + 0.5)

s = s1 + s2
d1 = datetime(*strptime(s[:14], "%Y%m%d%H%M%S")[0:6])
d1 = d1.replace(microsecond = mms2)
#
s = s1 + s3
d2 = datetime(*strptime(s[:14], "%Y%m%d%H%M%S")[0:6])
d2 = d2.replace(microsecond = mms3)
#
d = d2 - d1
print d.seconds
print d.microseconds

sorry for the noise )

ms2 = eval(s2) % 1

mms3 = int(ms3 * 1000000 + 0.5)

s = s1 + s2
d1 = datetime(*strptime(s[:14], "%Y%m%d%H%M%S")[0:6])
d1 = d1.replace(microsecond = mms2)

What about this:

py> import datetime
py> s1 = "20070619 115344.025"
py> p1, p2 = s1.split(".", 1)
py> d1 = datetime.datetime.strptime(p1, "%Y%m%d %H%M%S")
py> ms = int(p2.ljust(6,'0')[:6])
py> d1.replace(microsecond=ms)
datetime.datetime(2007, 6, 19, 11, 53, 44, 25000)

python2.3:
from time import strptime

py> ms = int(p2.ljust(6,'0')[:6])

ljust padds with space only in python 2.3. But thanks anyway your
solution is much cleaner !
