fetching images from web?

[randomtalk]

hi, i want to automate some tasks of gathering photos from web, i tried
urllib/urllib2, both ended up without much success (saved gifs with
only a border, nothing else)..

the code i used was:

>>> data = 
>>> urllib2.urlopen("http://aspn.activestate.com/ASPN/img/komodo_aspn_other.gif";)
>>>   #was looking through cookbook, so i used that as a sample image
>>> data = data.read()
>>> file = open("f:/test.gif", "w")
>>> file.write(data)
>>> file.close()


can someone suggest a better way (or what's wrong with urllib/urllib2)?
thanks alot!

recursive function return value problems

[randomtalk]

hi, i have the following recursive function (simplified to demonstrate
the problem):

>>> def reTest(bool):
... result = []
... if not bool:
... reTest(True)
... else:
... print "YAHHH"
... result = ["should be the only thing returned"]
... print "printing result: "
... print result
... return result
...
>>> reTest(False)
YAHHH
printing result:
['should be the only thing returned']
printing result:
[]
[]

I don't understand why results are returned twice? is there something
special i missed about recursive functions?

Re: recursive function return value problems

[randomtalk]

the final returned value is: []

the two values printed is (note i only have one print statement
printing "print result",. however, in the actualality, it's printed
twice):
printing result:
['should be the only thing returned']
printing result:
[]

therefore, sadly, i don't thinkg you've understand my problem
correctly..

download full sites?

[randomtalk]

hi, does anyone know of any package that will download a full site for
offline viewing? It will change all url to match local urls and follow
a logical structure (the site's structure would be suffice).. Please
tell me if you have heard of such a package.. thanks alot :D

Hello everyone!
i have the following test code:
class temp:
def __init__(self):
self.hello = "hello world!"
def printworld(self):
print(self.hello)
t = temp()

and i tried to call profile('t.printworld()')

but i received the following error:
Traceback (most recent call last):
  File "", line 1, in ?
TypeError: 'module' object is not callable

I'm not sure what is wrong exactly, if anyone can point me to the
right direction, it would be much appreciated!

append function problem?

[randomtalk]

hello, recently i tried to use list.append() function in seemingly
logical ways, however, i cannot get it to work, here is the test code:

>>> seed = [2, 3, 4, 5]
>>> next = 7
>>> seed1 = seed.append(next)
>>> seed1
>>> print(str(seed1))
None
>>> def test(lst):
... print(str(lst))
...
>>> test(seed.append(next))
None

I'm using Activestate python (latest) on win xp sp2..

I'm not sure why seed1 and the function doesn't recognize the list..

If anyone can point out where i'm going wrong would be much
appreciated!
Thanks in advance!

Is there such a method that does the opposite of sting.split? thanks
alot!

returning none when it should be returning a list?

[randomtalk]

hello, i have another problem i feel that i have to be missing
something.. Basically, i've written a recursive function to find all
the prime up to a number (lim).. here is the function:

The function basically takes in a list of all the prime number found,
it takes the next number to be tested for (next) and the limit it will
go up to. It divide next by the list of previous prime numbers if next
is not bigger than lim, count up all the times where it's not evenly
divdided, if the result is equal the length of prime number, then we
have another prime number, lather rinse and repeat :)

def findPrime(seed, next, lim):
print("seed: " + str(seed) + " next: " + str(next) + " lim: " +
str(lim))
print(seed)
if(next >= lim):
print(seed)
return seed
else:
count = 0;
for num in seed:
modu = math.modf(float(next)/float(num));
if(modu[0] > 0):
count += 1
if(count == len(seed)):
seed.append(next)
findPrime(seed, next+2, lim)
else:
findPrime(seed, next+2, lim)

As you can probably see, i've printed the value of seed up until the
point where i'm returning the seed, however, the function still returns
None..

I'm not sure what "falls off the end" of the function means, i searched
online, it seems to mean that the function has reached the end
prematurely and returned a default identifier to signal success or
not.. Can you please explain what that means?

Other than that, thanks alot for all those who posted! It's been very
educational!
