PyQt training in Python – Learn how to install and use Cute in Python

Herbert Huffner

Python is an integrated environment for all-purpose software development. Other important features of Python include its high level, object orientation, script and open source. 

Continuing with the article on education PyQt Python in this case we will talk.

Python was designed in 1991 by Khidofan Rossum of the Netherlands. The philosophy behind Python is based on two important principles: high readability and high relative efficiency. In addition to this topic, you can also take a look at learning how to learn machine learning with Python .

Kheidofan’s goal of Python Design was to create an alternative to the ABC programming language that could process exceptions. PyQt is one of the Python subsets that we will get to know a little later.

Python programming language

The number of keywords in the Python language is very limited, but it has very large libraries. In this programming language, unlike other languages, especially those that follow the rules of the C language, the code blocks are not defined in parentheses and are specified by moving the text forward using the space character.

In this way, a certain number of spaces are placed at the beginning of the line corresponding to each block of code and the internal blocks accept more distances. Using this method, different blocks are automatically sorted. This feature is known in Python as the off-side rule.

Python supports a variety of programming models, such as object-oriented programming as well as grammatical and function-oriented programming, and uses a dynamic system to identify the type of variables. Another important topic to know is data science training with Python .

Python, which is a fully object-oriented language, is one of the interpreter programming languages ​​that has very similar features to interpretive languages ​​such as Ruby, Scheme, Smalltalk, and TCL. This language benefits from automatic memory management and is managed by the Python Software Foundation.

Python Grammar

Python’s goal is to make the language very readable. For this reason, it tends towards a visual layout without noise and most of its keywords are in English. This is while other languages ​​use punctuation. Python requires less vocabulary as well as fewer syntactic exceptions and special cases compared to other traditional languages ​​such as Pascal and C.

Conditions and controls in Python

This condition executes a block of code until it reaches else or elif.

For

It is placed as a repeating loop on an object that must be repeated several times in a row. This command assigns a value to each local variable to be used by the corresponding block.

 

Class

This command, after executing a block of code, joins its local space to another class for use in object-oriented programming.

def

This command defines a function.

with

This command is responsible for enclosing the code block to the text manager.

It should be noted that each of these conditions has special semantic rules. For example, one of the features of the def condition, unlike other conditions, is that this condition does not execute its block quickly.

Compare Python to a superior language called Java

Recently, the Python programming language has become one of the most popular programming languages ​​in the world due to its simple syntaxes, extensive and modern data types, and powerful and extensive commands and libraries.

Although these programs run slower than programs written in Java, they often take less time to develop. Programs written in Python are 3 to 5 times shorter than their Java equivalent counterparts. This significant difference is due to the dynamic typing of the Python language. It remains to be seen how much Python developer will earn .

 

Learn PyQt training in Python!

PyQt is a Python multi-platform connection that is one of the suggested alternatives to programming the graphical user interface in Python and is used instead of TK Inter, which is associated with Python. PyQt, like Qt, is free software and a Python plugin. PyQt is developed by the British computer company River Bank.

Cute Pie is actually a tool to use Cute in the program. To understand this phrase, it is better to first get acquainted with the concept of cue!

Q is a software framework for creating graphical interfaces that are supported by Nokia for use in software products, including computer software and smartphones.

Because Qt is a multi-platform, it can run all programs written with Qt and Python on all different operating systems.

Modules available in PyQt

PyQt has a set of different modules, each of which has specific tasks.

The foot of the cue has important and various parts that we will examine in the following:

 QtCore

The QtCore module contains many non-graphical classes. This module is the core and contains important parts such as the event loop and the signal and slot mechanism.

 

 QtGui

This module includes all graphic classes.

 QtNetwork

This module includes classes that are used to build server-side and client-side applications based on TCP or UDP protocols. HTTP, FTP and DNS client classes are included in this module.

 QtOpenGL

This module uses OpenGL to create and create work on 3D images.

 QtScript

This module allows JavaScript to run written programs. In other words, this module provides development and scripting for users.

 QtSql

This module allows communication with Sql-based databases and includes a database manager.

 QtSvg

The functions used to display Svg files are placed in this category of modules.

 QtTest

The functions used to test the components of programs written by Python and Qty fall into this category of modules.

 QtXml

The classes in this module provide the SAX and DOM interfaces for the QML XML parser.

 

 QtAssistant

This module allows you to internalize QtAssistant software in applications written using Python and Qt. This will internalize the documentation in the program itself without having to create a separate section.

 QtDesigner

This module provides the basis for the development of QQ design by PyQt. Making a new plugin or element at the foot of the cube and using it in the design environment like other graphic objects is an example of this.

 QAXContainer

This module allows the written program to communicate with COM and Active X objects.

 Qt

This module includes all the modules mentioned above. If the programmer uses this module, he will no longer need to know the function module he needs. Loading the QT framework and over-occupying memory are some of the problems with this method.

 uic

Classes created by Qt Designer to work with ui files are included in this module.

Tools available in PyQt training in Python

PyQt also has useful and important tools that make it easy to work in programming. Here are some important tools:

Tools fall into this category that make programming easy and fast.

 

Pyuic4

This tool is equivalent to uic and is responsible for converting graphical interface files created by the QtDesigner tool to Python source code.

 Pyrcc4

This tool is equivalent to rcc Qt framework, which allows you to convert source files such as photos, icons or any other custom file to Python source code, as well as internalize an independent executable file.

 Pylupdate4

This tool, which is used to create or update the program vocabulary file, is equivalent to the lupdate tool. This tool allows you to create a st file and translate it using software such as Qt Linguist for use in the program. This tool also improves the ease of developing multilingual applications.

In August 2009, the current owner of Qt Tools, Nokia, launched PySide, which offers similar capabilities under the LPG. But failed to reach an agreement with River Bank!

Install PyQt on Windows

Installing Cute Pie in Windows is a very simple and easy task. Sometimes it is necessary to add the path installed in the Windows operating system to Environment Variables or to local PATH variables. To do this, add the Python interpreter path and, if necessary, the quote to the environmental variables.

Right-click on My Computer and select properties from the available options, go to the Advanced tab, and by clicking on Environment Variable, edit the PATH variables and access the environmental variables. In the following, we will have a look at the article on what to know about hacking with Python Nir.

 

 

In order to use PyQt, download the installer binary file with an approximate size of 16 MB from the official site and then install it on your Windows. This file contains the following tools:

By installing this file, you have installed all the tools and files you need and you can easily use them.

Install PyQt on Linux

The steps for installing Coot Pie on Linux are different than on Windows. Some people tend to download and compile the latest packages. Others choose to use operating system installers to avoid compile problems. However, the following packages must be installed on your system. It is important to follow the order in installing these packages.

Qt, which can contain only major libraries, or include a variety of tools such as Qt, Qt Designer, and..

The names of the packages vary according to the type of operating system as well as different distributions. In Ubuntu repositories, for example, the package name PyQt is python-qt4.

Share any problems created during the various stages of installation with the site forums.

  1. The process of building an application with PyQt
  2.  Convert PyQt file to Python code and run it
  3. Converting Cute pie files to Python code is done using two manual methods and converter software.

A handy way to teach PyQt in Python

Step 1: Build the form and save it

In the first step, you will start designing a form in PYQT4 using the Designer tool. Then save the created form with the .ui extension.

Step 2: Implement PYUIC4

In the Taskbar, click Start and then Run. A box will open for you. Type CMD in it and click Ok.

Find the pyuic installation path and enter its address in the opened box.

 

 

Step 3: Final preparation to convert the file to Python code

In this step, copy the address of the created file that you saved with the .ui extension and then select an address to save the file.

Step 4: Convert the file to Python code

Enter the following code in the CMD box and look at the result where you selected the .pyw file to save.

 

 

The converter software will convert the file to Python code directly for you without your intervention.
