​Top 5 Python GUI Libraries 🖥

A Graphical User Interface (GUI) is the first thing your user sees and interacts with when he opens your application or website. A user interface usually includes a host of visual elements like icons, buttons, graphics, displayed text, and several other forms of input, like checkbox, text input boxes, and such. The goal behind this post is to help you to find the right framework for building interactive GUIs with the several GUI frameworks Python has to offer.

▪️PyQt5
The PyQt package is built around the Qt framework, which is a cross-platform framework used for creating numerous applications for various platforms. It also offers the QtGui and the QtDesigner module, which provide numerous visual elements that the developer can implement with a simple drag and drop.

▪️Tkinter
Tkinter was created to equip modern developers with a standard interface to the Tk GUI toolkit with its Python bindings. In Tkinter’s world, most of the visual elements that we’re familiar with are called widgets, and each of these widgets offers a different level of customizability.

▪️Kivy
Kivy is an open-source GUI framework for building some of the most intuitive user interfaces encompassing multi-touch applications that implement Natural User Interface (NUI). With Kivy, interface designers can code once and deploy to multiple platforms.

▪️wxPython
wxPython allows Python developers to create native user interfaces that add zero additional overhead to the application. The cross-platform capabilities of wxPython allow deployment to platforms like Windows, Mac OS, Linux, and Unix-based systems with little to no modifications.

▪️PyGUI
PyGUI is a graphical application cross-platform framework for Unix, Macintosh and Windows. Compared to some other GUI frameworks, PyGUI is by far the simplest and lightweight of them all. PyGUI inserts very less code between the GUI platform and Python application, hence the display of the application usually displays the natural GUI of the platform.

How to handle messy CSV files 🐍

🔸CleverCSV is a Python package for detecting the dialect of CSV files with high accuracy. It is modeled on the way in which a human would determine the dialect: by looking for patterns that result in a regular tabular structure with “clean data” in the cells (such as numbers, dates, etc.).

The package is designed to help a data scientist with messy CSV files. It also provides a handy command line tool that can standardize a messy file or generate Python code to import it.

⚙️Installation
pip install clevercsv[full]

New Python programmable calculators 💻

♦️Dallas-based Texas Instruments’ latest generation of calculators is getting a modern-day update with the addition of programming language Python. The goal is to expand students’ ability to explore science, technology, engineering and math through the device that’s all-but-required in the nation’s high schools and colleges.

♦️Along with the addition of Python, the new model of calculator will also have familiar features like durability, a long-lasting battery and full-color screen. The device is also approved to use on college entrance exams as well as Advanced Placement and International Baccalaureate tests.

Assert Statements in Python

♦️Python’s assert statement is a debugging aid that tests a condition. If the condition is true, it does nothing and your program just continues to execute. But if the assert condition evaluates to false, it raises an AssertionError exception with an optional error message.

♦️The goal of using assertions is to let developers find the likely root cause of a bug more quickly. An assertion error should never be raised unless there’s a bug in your program. They’re not intended to signal expected error conditions, like “file not found”, where a user can take corrective action or just try again.

Complex Numbers in Python 🐍

Most general-purpose programming languages have either no support or limited support for complex numbers. Python is a rare exception because it comes with complex numbers built in.

The quickest way to define a complex number in Python is by typing its literal directly in the source code:
>>> z1 = 1 + 2j

You can also use a built-in Python function, complex(). It accepts two numeric parameters. The first one represents the real part, while the second one represents the imaginary part denoted with the letter j in the literal you saw in the example above:

>>> z2 = complex(1, 2)
>>> z1 == z2
True

To get the real and imaginary parts of a complex number in Python, you can reach for the corresponding .real and .imag attributes:

>>> z2.imag
2.0

Note that both properties are read-only because complex numbers are immutable, so trying to assign a new value to either of them will fail.
