Python Practice Project

Calories Burned Calculator

DESCRIPTION

Curious about how many calories you burned during exercise? You can estimate your calorie expenditure by using a simple calculator. In this exiciting Python practice project  you will have to create a desktop application with Python and the PyQt5 platform to calculate the energy expenditure of multiple sports like running or boxing and routine activities such as ironing  or yoga. You will create a front so that the user can enter several variables like the age or weight and the application will automatically display the calories burned during the exercise along with two other ratios. You will have to build dropdown menus, selection buttons and blank spaces to enter data.

Main parts

– The construction of the skeleton of the app with PyQt widgets, the graphical user interface.
– Populate the app with the data provided in a csv file and implement the calculations defined in the instructions to find out the calories burned.

It is also a beginner object oriented programming exercise, since you will you have to create classes and write methods to make the app work.
PyQt5 is one of the options provided by Python (like Tkinter)  to build easily interactive desktop applications. You can install it as any other Python library (pip install) and it allows to design the front-end and combine it with the back-end.

INSTRUCTOR

Daniel Gunn is a software developer based in the UK. He holds a Computer Science degree, and he currently works as a freelance programmer specialized in Python.

DOWNLOAD / CONTENT

After purchase, you will receive an email with a ZIP file. It is also a digital download always available on your Practity account.
The ZIP file includes:

1. INSTRUCTIONS: A PDF with the project description. It includes a short guidelines section, and a screenshot of the app so can visualize what you have to build.
2. DATA: A csv file with all the data related to the activities and their categories.
3. SOLUTIONS:
   – A .py file with the project source code (250 lines). The script provided in the solutions has been written by a senior developer, so it is clean and easy to understand. A great way to learn and adopt right habits to create quality software.
   – A PDF with detailed explanations of each chunk of code (13 pages). The instructor explains step by step what the code does and why.

WHAT YOU WILL PRACTICE

– Classes and methods.
– PyQt elements: QWidget, QApplication, QMessageBox,QComboBox, QPushButton, QLabel, etc.
– Conditional statements
– Loops (for) + enumerate
– Functions
– Read csv files
– Errors and exceptions
– Formatted String Literals (f-strings)
– “__init__” method

REQUIREMENTS

This Python practice project is highly recommended for Python intermediate students who have attended Python courses and feel comfortable with core Python concepts like loops, methods or functions definition.  It is an excellent Python exercise to start building desktop applications and get familiar with OOP and the great PyQt platform.
