You could try using: urlllib.urlretrieve ...it may be faster.

Re: ZipFile and file rigths

[ralobao]

You can use os.chmod to fix it.

Here the description:

os.chmod

Docstring:
chmod(path, mode)

Change the access permissions of a file.

Re: beginner question fibonacci

[ralobao]

The case is that Python in attribution commands solves first the right
side, so he atributes the vars.

So the a+b expression is executed first.

Problem while trying to extract a directory from a zipfile.

[ralobao]

I have this code:

try:
file = zipfile.ZipFile(nome_arquivo)
Gauge.start() #inicia o Gauge
for element in file.namelist():
try:
newFile = open(diretorio + element,"wb")
except:
newFile = open(diretorio + element + '/',"w")
# Gauge
percent = percent + 10
Gauge.update(percent)
Gauge.set_text("Extraindo" + element)
# Extrai
newFile.write(file.read(element))
newFile.close()

But when i try to extract an zipfile with a directory in it the code
returns me an IOErro exception: "It is a directory"

Please how can i solve it ?
