Upload Files In Python Development

How To Upload Files In Python Development

File uploading is necessary for various software programs to carry out specific tasks. Many web and desktop apps demand users to upload the files in the regular file format, such as an image file, audio file, etc. Most of the file uploading occurs via web programs.

Python offers a variety of packages that make HTTP data transport simpler. Every developer who develops an Android app using Python should be familiar with the usefulness and requirement of file uploading.

Developers can select from a variety of packages when uploading a file to a Python program. So, here, in this article, we are going to discuss various methods of uploading files in Python.

Methods to Upload Files in Python Program

A Python program can upload files in a variety of methods. Some might need script functionality and HTML buttons, and some can upload files directly through the app.

Utilizing the os module of Python

With the help of this method, we can define specific actions utilizing HTML code. Also, HTML supports a variety of characteristics for all the HTML elements.

To set the Python program for execution, you may use the <form> along with the action attribute. Also, the HTML form is able to upload a file with the help of the enctype attribute's "multi-part/form-data" value. Finally, to upload the chosen file, you will require the input tag along with the filename attribute.

With the help of the os module, the Python program can communicate with the operating system. Hence, you should utilize the os module in the Python application as the file is stored as an operating system component.

So, in order to handle the actions related to the operating system, you must first import the OS module. The next step is to build an identifier that would conserve the filename in order to upload it. Further, to decide if the name of the file is already existing or not use the IF condition.

Next, strip the file's leading absolute path and extract the filename using the os.path.basename() function. In order to store that path, you may utilize another identifier. Finally, now you may open the file, write it, and read it on the server.

Utilizing the requests library

The requests module has a number of predefined methods that Python programmers can use to send HTTP requests. A response object including response data like content, encoding, status, etc. is delivered in response to an HTTP request.

This allows you to encode the PUT and POST data without individually encoding the URLs using query strings or using any other form-encoding techniques. As it is not an in-built library, you may need to use the "$ pip install requests" command to install it.

Now that the Python file has been created, you may import the requests into the program. This technique uses the requests library, thus you must first import it into the Python program before using it.

After that, open your datafile.txt file in read binary mode. Thereafter, form a string identifier that includes the URL. Next, you may use the post() method, passing both the opened file and the URL as a Python dictionary.

You can now decide if the test result (test_res) is acceptable or not. If all goes as expected, you may display a success text as well as the finalized text. If not, you may instruct the user to upload it again.

Utilizing Filestack API

You can also utilize the Python SDK and the Filestack Application Programming Interface (API) to upload files into a Python program. You may install this SDK using the pip install filestack-python command.

Now, after installing, start your Python program with the filestack SDK. After that, use the Filestack API key to create a Client instance. This Client will take care of the difficult operations in the software on your behalf.

Importing the Filestack API is necessary for your Python program. After importing the Client module from the filestack, enter the API key that you received during registration. Put it in a different variable.

Next, establish a connection to the file link you want to upload, and then give the file path the parameter value in the upload() method. Now, the final step is to display the filelnk file.

Conclusion

So, to conclude all the methods, the third method, API calls, is the least effective and takes up more time in comparison to others. The first approach is used exclusively to create web applications, while the second method is used to create standalone or desktop programs. The OS module is faster than the requests library because it makes more frequent system calls. However, using the request module to upload files is simpler.
