Python GUI Frameworks

Python offers many different libraries and frameworks for the development of Graphical User Interfaces (GUIs). Many of these tools can create cross platform GUI applications with varying degrees of customizability. At a base level, these frameworks provide the user the ability to create windows, labels, buttons, and canvases (for drawing things) among other graphical features for their applications.

Python Programming Advanced Topics

When working on python projects, using "virtual environments" allows for your project to be run using its own isolated python binary. The packages that this project uses also exist separately from the python packages installed locally on one's system. This allows for greater organization while working within projects.

Virtual Environments

Concurrency and parallelism in Python are mainly handled by 2 built-in modules: Threading and multiprocessing. Threading allows Python to make use of multiple threads in order to speed up programs that are I/O dependent. Alternatively, multiprocessing allows Python to use multiple processes to speed up CPU bound scenarios.

Additionally, web servers, databases, and distributed networks also make use of the asyncio module. Asyncio allows for concurrent code so that the aforementioned systems don't have wait on execution

Concurrency and Paralellism in Python

Python is widely used for deep learning  with various reasons.

1. Python offers concise and readable code.

2. To reduce development time, programmers turn to a number of Python frameworks and libraries like kearas, TensorfFlow, and NumPy.

3.  Python is supported by many platforms including Linux, Windows, and macOS.

4. Python is the language that people Google more than any other.


Deep learning with Python

Quantum computing is an emerging field that appears to be more and more difficult to avoid in a vast number of fields including physics, business, mathematics, chemistry, and more notably, data science. One such aspect of quantum computing that attracts the minds of many, especially data scientists, is its potential in advancing our knowledge in optimization problems. As such, it may be invaluable to understand the basics of quantum computing and how to start quantum programming now, even before the widespread availability of quantum computers. Even better, companies like Google, Microsoft, IBM, Rigetti, and more have developed their own open-source development kits to begin learning quantum computing. One such software package is called QuTip within Python.

Popular Tools for Python

When developing python applications, you often need to use libraries or packages that aren't included in python's standard library. In order to keep track of the required packages and libraries that your project depends on, you can make use of a package manager to install packages and manage dependencies. Python's documentation officially recommends the use of pipenv, but other package managers exist as well, such as pip and poetry.

Package Management

Python has an assortment of tools that are interwoven with the Internet. The language is frequently used both for web development and for interacting directly with the web.

Python and the Web

Python currently ranks third in usage behind C and Java. The original Python was developed in the 1980s by Guido van Rossum and was first released in 1991. Python 2.0 saw release in 2000. The current Python 3.0 was released in 2008 and represented a major revision emphasizing the design philosophy of code readability.

OpenCV is a very useful tool for image recognition. It is often used in tandem with machine learning libraries, but also allow for relatively simple image manipulation tools such as rotating, resizing and changing data values.

Python is the scripting language of ArcGIS. ArcGIS includes a Python API, ArcPy, that gives users access to all geoprocessing tools as well as scripting functions and specialized modules that help them automate GIS tasks. Users can write scripts that use ArcPy in conjunction with a diverse array of functions provided through Python's standard and third-party libraries. They can execute Python commands and scripts with ArcGIS Notebooks, in the Python window, through script tools, or run Python outside of ArcGIS. However Python is run, the commands work the same way and use the same geoprocessing tools.

Geoprocessing with Python

Python libraries are called "modules". They are a reusable chunk of codes that can be included in your programs to provide various functionalities in the form of different objects or functions. For example, there are modules that have functions you can use in your code to test if certain files exist on your hard drive. Likewise,  there are other modules that have functions for implementing web-server or web-browser functionality or to work with images or create charts and graphs; etc.
#
The Python standard library comes with the Python package and installs with it when Python is installed on your computer. 
#
Additionally, there is a growing number of Python's third-party libraries that canbe imported into your scripts to executes tasks that outstrip the limits of the standard library.

Pillow is a fork of the discontinued Python Imaging Library (PIL) and is the most popular package for image processing. It allows for the creation, editing, and exporting of images, as well as including support for a large number of image file formats. Pillow is not included with a Python installation and must be installed with a package manager such as pip.
