Hello,
I have written a script which fetches a distribution, given the URL. After downloading the distribution, it compares the md5 hashes to verify that the file has been downloaded properly.
This is how I do it.
def download(package_name, url):
import urllib2
downloader = urllib2.urlopen(url)
package = downloader.read()
package_file_path = os.path.join('/tmp', package_name)
package_file = open(package_file_path, "w")
package_file.write(package)
package_file.close()
I wonder if there is any better(more pythonic) way to do what I have done using the above code snippet.
Also, once the package is downloaded this is what is done:
def install_package(package_name):
if package_name.endswith('.tar'):
import tarfile
tarfile.open('/tmp/' + package_name)
tarfile.extract('/tmp')
import shlex
import subprocess
installation_cmd = 'python %ssetup.py install' %('/tmp/'+package_name)
subprocess.Popen(shlex.split(installation_cmd)
As there are a number of imports for the install_package method, i wonder if there is a better way to do this. I`d love to have some constructive criticism and suggestions for improvement.
Also, I have only implemented the install_package method for .tar files; would there be a better manner by which I could install .tar.gz and .zip files too without having to write seperate methods for each of these?
