But this works well only for small files. It is possible to extract. I hope I understood the question right, which is: how to download a file from a server when the URL is stored in a string type? The following functions and classes are ported from the Python 2 module urllib as opposed to urllib2. They might become deprecated at some point in the future. You can use wget which is popular downloading shell tool for that. Here is an example. Yes, definietly requests is great package to use in something related to HTTP requests.
For example, If I use the machine learning method, train a model that can recognize an image with the number bar code. If you are using Linux you can use the wget module of Linux through the python shell. Here is a sample code snippet. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

The answerer is still and quite active on SO. Why not just add a comment and ask? Cos a good answer that lasts the test of time is worth awarding. Also, we should start doing this for a lot of other questions to check whether answers are relevant today.
Especially when the sorting of SO answers are rather crazy, sometimes the out-dated or even worst answer goes to the top. On completion of the context or destruction of the temporary directory object, the newly created temporary directory and all its contents are removed from the filesystem.
The directory name can be retrieved from the name attribute of the returned object. When the returned object is used as a context manager, the name will be assigned to the target of the as clause in the with statement, if there is one.
The directory can be explicitly cleaned up by calling the cleanup method. Otherwise, errors will be raised in whatever context cleanup occurs the cleanup call, exiting the context manager, when the object is garbage-collected or during interpreter shutdown. Creates a temporary file in the most secure manner possible.
The file is readable and writable only by the creating user ID. If the platform uses permission bits to indicate whether a file is executable, the file is executable by no one. The file descriptor is not inherited by child processes. Unlike TemporaryFile , the user of mkstemp is responsible for deleting the temporary file when done with it.
If suffix is not None , the file name will end with that suffix, otherwise there will be no suffix. If prefix is not None , the file name will begin with that prefix; otherwise, a default prefix is used.
The default is the return value of gettempprefix or gettempprefixb , as appropriate. If dir is not None , the file will be created in that directory; otherwise, a default directory is used. There is thus no guarantee that the generated filename will have any nice properties, such as not requiring quoting when passed to external commands via os.
If any of suffix , prefix , and dir are not None , they must be the same type. If they are bytes, the returned name will be bytes instead of str. If text is specified and true, the file is opened in text mode. Otherwise, the default the file is opened in binary mode. Prior to this, only str was allowed. Creates a temporary directory in the most secure manner possible. The directory is readable, writable, and searchable only by the creating user ID. The user of mkdtemp is responsible for deleting the temporary directory and its contents when done with it.
The prefix , suffix , and dir arguments are the same as for mkstemp. Return the name of the directory used for temporary files. This defines the default value for the dir argument to all functions in this module.
Python searches a standard list of directories to find one which the calling user can create files in. The list is:. The directory named by the TEMP environment variable. The directory named by the TMP environment variable. The result of this search is cached, see the description of tempdir below.
Previously it would return any tempdir value regardless of type so long as it was not None. Strengthen your foundations with the Python Programming Foundation Course and learn the basics. Now check your local directory the folder where this script resides , and you will find this image: All we need is the URL of the image source. You can get the URL of image source by right-clicking on the image and selecting the View Image option.
To overcome this problem, we do some changes to our program:. Setting stream parameter to True will cause the download of response headers only and the connection remains open.
This avoids reading the content all at once into memory for large responses. A fixed chunk will be loaded each time while r. All the archives of this lecture are available here. So, we first scrape the webpage to extract all video links and then download the videos one by one.
It would have been tiring to download each video manually. In this example, we first crawl the webpage to extract all the links and then download videos. This is a browser-independent method and much faster! One can simply scrape a web page to get all the file URLs on a webpage and hence, download all files in a single command- Implementing Web Scraping in Python with BeautifulSoup This blog is contributed by Nikhil Kumar.
