Hi,
Pls take a look at this code:
--
>>> t1 = "1130748744"
>>> t2 = "461"
>>> t3 = "1130748744"
>>> t4 = "500"
>>> time1 = t1+"."+t2
>>> time2 = t3+"."+t4
>>> print time1, time2
1130748744.461 1130748744.500
>>> float(time2) - float(time1)
0.03934332275391
>>>
Why are there so m
Thanks Szabolcs and Laurence, it's not the crash of python but the
crash of cygwin. We can locate the line number but when we submit the

Regards,
Johnny

First, I want to know whether the python interpreter translate the
code directly into machine code, or translate it into C then into
machine code?
Second, if the codes are translated directly into machine codes, how
can I translate the codes into C COMPLETELY the same? if the codes are

It looks like there isn't a last word of the differrences

def __init__(self):
self.member = 1
def getMember(self):
return self.member
a = A()

for your help. :)

Hi,
I've met a problem to understand the code at hand. And I wonder
