In this tutorial, you operate in Scientific Mode and use Matplotlib and NumPy packages to run and debug a Python code with data visualization. Before you start, ensure the following is installed: Conda interpreter. Matplotlib package. Creating a Scientific project Create a PyCharm project with the scientific settings predefined. PyCharm Software Application Tutorial PyCharm is an IDE (Integrated Development Environment) where you can write programs and make use of a variety of Python tools. PyCharm is an Integrated Development Environment (IDE) that provides tools for writing efficient code. It supports various frameworks such as Django, Flask, and Pyramid.

PyQt5 is a toolkit for creating Python GUI applications. As a cross-platform toolkit, PyQt can run on all major operating systems (Unix, Windows (Mac).
This article describes how to install Python + PyCharm + PyQt5.
With PyQt5, the GUI is designed in two ways:
- directly using the code to design the interface
- using QtDesigner to visualize the design, and then convert the resulting .ui file into a .py file.

QTDesigner
Use QTDesigner to generate a GUI interface and convert it to a .py file using PyUIC.
Select Tools->ExternalTools->QTdesigner.
In the QT Designer interface, a GUI creation interface will pop up for the first time, click on create to automatically generate a GUI interface.
Save the interface as Untitled.ui file.
Back to the PyCharm project interface, there is an extra .ui file under the project list.
