Welcome folks today in this post we will be showing progressbar animation in pyqt5 when downloading files in python. All the full source code of the application is shown below
Get Started
In order to get started we need to install the following library using the pip command as shown below
pip install urllib
pip install pyqt5
After installing these libraries make an app.py file and copy paste the following code
app.py

Now if you execute the above script by typing the below command
python app.py
So you will see it will download the image file with progressbar animation from the given path and store it as profile.jpg in my root directory as shown below
