Alternative of urllib.urlretrieve in Python 3.5

I am currently doing a course on machine learning in UDACITY . In there they have written some code in python 2.7 but as i am currently using python 3.5 , i am getting some error . This is the code

import urllib
url = "https://www.cs.cmu.edu/~./enron/enron_mail_20150507.tgz"
urllib.urlretrieve(url, filename="../enron_mail_20150507.tgz")
print ("download complete!")

I tried urllib.request .

  import urllib
  url = "https://www.cs.cmu.edu/~./enron/enron_mail_20150507.tgz"
  urllib.request(url, filename="../enron_mail_20150507.tgz")
  print ("download complete!")

But still gives me error .

urllib.request(url, filename="../enron_mail_20150507.tgz")
TypeError: 'module' object is not callable

I am using PyCharm as my IDE .

Solution

You'd use urllib.request.urlretrieve. Note that this function "may become deprecated at some point in the future", so you might be better off using the less likely to be deprecated interface:

# Adapted from the source:
# https://hg.python.org/cpython/file/3.5/Lib/urllib/request.py#l170
with open(filename, 'wb') as out_file:
    with contextlib.closing(urllib.request.urlopen(url)) as fp:
        block_size = 1024 * 8
        while True:
            block = fp.read(block_size)
            if not block:
                break
            out_file.write(block)

For small enough files, you could just read and write the whole thing and drop the loop entirely.
