The open method accepts two parameters, the path to the local file and the mode in which data will be written. With open( '/Users/scott/Downloads/cat2.jpg', 'wb') as f: Therefore, this script works only in Python 2. Note that in Python 3, urllib2 was merged in to urllib as urllib.request and urllib.error. The urlopen method of the urllib2 module returns an object that contains file data. Using the urllib2 ModuleĪnother way to download files in Python is via the urllib2 module. We've included it here due to is popularity in Python 2. Because of this, I wouldn't recommend using it in favor of one of the methods below. Note: This is considered a "legacy interface" in Python 3, and it may be deprecated at some point in the future. You should see your downloaded file named "cat.jpg". Run the above script and go to your "Downloads" directory. Keep in mind that you can pass any filename as the second parameter and that is the location and name that your file will have, assuming you have the correct permissions. Finally, we call the urlretrieve method and pass it the url variable as the first argument, "/Users/scott/Downloads/cat.jpg" as second parameter for the file's destination. Next we create a variable url that contains the path of the file to be downloaded. In the above code, we first import the urllib.request module. Print( 'Beginning file download with urllib2.') Let's take a look at the following example: To use this method, you need to pass two arguments to the urlretrieve method: The first argument is the URL of the resource that you want to retrieve, and the second argument is the local file path where you want to store the downloaded file.
Specifically, the urlretrieve method of this module is what we'll use for actually retrieving the file. The urllib.request module is used to open or download a file over HTTP. In this article we will take a look at some of the most popular ways you can download files with Python. These are just a few of the applications that come to mind, but I'm sure you can think of many more. Here are just a few web application functions that require downloading files: The importance of file downloading can be highlighted by the fact that a huge number of successful applications allow users to download files.
Downloading files from different online resources is one of the most important and common programming tasks to perform on the web.
