In this section, we will go through a list of Python advanced tutorials. We will check out a few libraries of Python that we can use for different purposes.
Tkinter
Python tkinter, short for “Tk interface,” is a built-in library in Python used for creating graphical user interfaces (GUIs) for desktop applications. It is a standard Python interface to the Tk GUI toolkit, which is a popular cross-platform library for creating graphical interfaces.
Tkinter provides a simple and intuitive way to design and develop GUI applications using a wide range of widgets, such as buttons, labels, text boxes, checkboxes, and menus. These widgets allow users to interact with the program through various input and output mechanisms.
Tkinter is an attractive choice for developers looking to create simple to moderately complex GUI applications, as it is easy to learn and requires no additional installations, being part of the Python standard library.
SciPy
SciPy, which stands for Scientific Python, is an open-source library used in Python for scientific computing and technical applications. It builds upon the foundational capabilities of NumPy, another widely-used library for numerical computations in Python, and extends its functionality with additional modules for a wide range of scientific domains.
SciPy is commonly used by researchers, engineers, and data scientists to perform various tasks that require advanced mathematical functions and algorithms.
