Python download file requests
In this tutorial, you will learn how to download files from the web using different Python modules. You will download regular files, web pages, Amazon S3, and other sources. Also, you will learn how to overcome many challenges that you may counter, such as downloading files that redirect, downloading large files, multithreaded download, and other tactics. Then you write the contents of the variable into a file.
You can also download a file from a URL by using the wget module of Python. Install the python download file requests module using pip as follows:. In this code, we passed the URL along with the path where we will store the image to the download method of the wget module. In this section, you will learn to download from a URL that redirects to another URL with a. pdf file using requests. The URL is like the following:. In this code, the first step we specify the URL.
Then we use the get method of the requests module to fetch the URL, python download file requests. After redirection, the content will be in myfile variable. First, we use the get method of the requests module as we did before, but this time we will set the stream attribute to True.
Then we create python download file requests file named PythonBook. pdf in the python download file requests working directory and open it for writing. Then we specify the chunk size that we want to download at a time. We have set to bytes. Iterate through each chunk and write the chunks in the file until the chunks finished.
We imported the os and time modules to check how much time it takes to download files. The module ThreadPool lets you run multiple threads or processes using the pool. The URLs variable is a two-dimensional array that specifies the path and the URL of a page you want to download. Pass the URL to requests. get as we did in the previous section. Finally, open the file path specified in the URL and write the content of the page.
Now we can call this function for each URL separately, and we can also call this function for all the URLs at the same time.
The Progress bar is a UI widget of the clint module. To install the clint module, type the following command:, python download file requests. In this code, we imported the requests module and then from clint.
textui, we imported the progress widget. The only difference is in the for loop. We used the bar method of the python download file requests module while writing the content into the file. The output will be like the following:. In this code, we used the urlretrieve method and passed the URL of a file along with the path where we will save the file. The file extension will be.
If you need to use a proxy to download your files, you can use the ProxyHandler of the urllib module. Check the following code:. Then we made the request to retrieve the page. The urllib3 is an improved version of the urllib module. You can download and install it using pip:. You can use the shutil module when working with files. Now initialize the URL string variable like this:. Finally, we send a GET request to fetch the URL and open a file and write the response into that file:.
To download a file from Amazon S3, import boto3, and botocore. Boto3 is an Amazon SDK for Python to access Amazon web services such as S3. Botocore provides the command line services to interact with Amazon web services. Now initialize a variable to use the resource of a session. For this, we will call the resource method of boto3 and pass the service which is s You can use the asyncio module to handle system events.
It works around an event loop that waits for an event to occur and then reacts to that event. The reaction can be calling another function. This process is called event handling. The asyncio module uses coroutines for event handling. To use the asyncio event handling and coroutine functionality, we will import the asyncio module:. The keyword async tells that this is a native asyncio coroutine. Inside the body of the coroutine, we have the await keyword, which returns a certain value.
We also used the return keyword. In this code, we created an async coroutine function that downloads our files in chunks and saves them with a random file name and returns a message.

He loves writing shell and Python scripts to automate his work. Mokhtar, appreciate your effort in taking time to compile these tutorials. Thank python download file requests for sharing your knowledge to the world. More blessings to you bro!. Thank you very much for the kind words! Appreciate it so much, python download file requests.
That drives me to do my best. Have a great day. Dunno if my previous comment went through. Might be due to the link? Please feel free to delete this comment if the previous one is just waiting for moderation. Would you be willing to change your asyncio example? com to the front of it:. Thank you very much Evan! Appreciate it. I modified the code. Check it and tell me if there anything needs to be modified.
Looks much better, thanks for listening, python download file requests. timeout : async with session. get url as response: And so on. With this, python download file requests, the entire request can take no longer than seconds. This library can be used with any asyncio operation, not just aiohttp. Thanks for your care.
I updated the code and included the async module. But this timeout will be for each request, not the entire requests. I tested ThreadPool code, but nothing was downloaded. The reported time is fast, but without downloading any files. Thanks Mokhtar, i was actually looking for this.
