Welcome to CGPA CALCULATOR !

A Simple CGPA calculator using PyQt5.

Files

First you have install PyQt5 in your Python Version 3 using Command prompt.

What are the packages to be installed

PyQt5 , auto-py-to-exe and Qt Designer

What is Qt Designer

Qt Designer is the Qt tool for designing and building graphical user interfaces (GUIs) with Qt Widgets.

Create .Ui file and folders

We have to develop the graphical user interfaces (GUIs) for your application using QT Designer application. After develop the GUI, create folder for this file and save your .ui folder.

Switch to another file

All your files and folders are presented as a tree in the file explorer. You can switch from one to another by clicking a file in the tree.

Rename a file

You can rename the current file by clicking the file name in the navigation bar or by clicking the Rename button in the file explorer.

Delete a file

You can delete the current file by clicking the Remove button in the file explorer. The file will be moved into the Trash folder and automatically deleted after 7 days of inactivity.

Convert .ui to .py

You want to convert .ui file to .py by clicking Command Prompt. You have to type cd >Location of the file< and click enter.Now you have to type pyuic5 -x Filename.ui - o Filename.py and click enter. Now python has been created.

Source Code

You have to type the following code under def retranslateUi(self, MainWindow):

self.doubleSpinBox.setMinimum(0)  
self.doubleSpinBox.setDecimals(3)  
self.doubleSpinBox_2.setMaximum(10)  
self.doubleSpinBox_2.setMinimum(0)  
self.doubleSpinBox_2.setDecimals(3)  
self.doubleSpinBox_3.setMaximum(10)  
self.doubleSpinBox_3.setMinimum(0)  
self.doubleSpinBox_3.setDecimals(3)  
self.doubleSpinBox_4.setMaximum(10)  
self.doubleSpinBox_4.setMinimum(0)  
self.doubleSpinBox_4.setDecimals(3)  
self.doubleSpinBox_5.setMaximum(10)  
self.doubleSpinBox_5.setMinimum(0)  
self.doubleSpinBox_5.setDecimals(3)  
self.doubleSpinBox_6.setMaximum(10)  
self.doubleSpinBox_6.setMinimum(0)  
self.doubleSpinBox_6.setDecimals(3)  
self.doubleSpinBox_7.setMaximum(10)  
self.doubleSpinBox_7.setMinimum(0)  
self.doubleSpinBox_7.setDecimals(3)  
self.doubleSpinBox_8.setMaximum(10)  
self.doubleSpinBox_8.setMinimum(0)  
self.doubleSpinBox_8.setDecimals(3)  
  
self.spinBox.setMaximum(35)  
self.spinBox.setMinimum(0)  
self.spinBox_2.setMaximum(35)  
self.spinBox_2.setMinimum(0)  
self.spinBox_3.setMaximum(35)  
self.spinBox_3.setMinimum(0)  
self.spinBox_4.setMaximum(35)  
self.spinBox_4.setMinimum(0)  
self.spinBox_5.setMaximum(35)  
self.spinBox_5.setMinimum(0)  
self.spinBox_6.setMaximum(35)  
self.spinBox_6.setMinimum(0)  
self.spinBox_7.setMaximum(35)  
self.spinBox_7.setMinimum(0)  
self.spinBox_8.setMaximum(35)  
self.spinBox_8.setMinimum(0)  
self.pushButton.clicked.connect(calculateCGPA)

Define CalculateCGPA:

    ui.label_18.setText("9.8")  
    Totalcredits = ui.spinBox.value() + ui.spinBox_2.value() +  \       
                           ui.spinBox_3.value() + ui.spinBox_4.value() + \  
                          ui.spinBox_5.value() + ui.spinBox_6.value() +\ 
                          ui.spinBox_7.value() +ui.spinBox_8.value()  
    CGPA = (ui.doubleSpinBox.value() * ui.spinBox.value() +  
            ui.doubleSpinBox_2.value() * ui.spinBox_2.value() +  
            ui.doubleSpinBox_3.value() * ui.spinBox_3.value() +  
            ui.doubleSpinBox_4.value() * ui.spinBox_4.value() +  
            ui.doubleSpinBox_5.value() * ui.spinBox_5.value() +  
            ui.doubleSpinBox_6.value() * ui.spinBox_6.value() +  
            ui.doubleSpinBox_7.value() * ui.spinBox_7.value() +  
            ui.doubleSpinBox_8.value() * ui.spinBox_8.value()) / Totalcredits  
  
    ui.label_18.setText(str(CGPA))

Run

You can run the file in pycharm or Microsoft visual studio before convert to .exe. Using this you can check whether the application is working correctly or not.
