Python is one of the simplest programming languages among others. It was created to simplify learning a programming language and provide beginners with programming fundamentals. Python is a very secure programming language with many built-in libraries, many functions can be performed by simply pasting the appropriate code from the library. Additionally, Python code is platform-independent, making it possible to execute on any platform, which is another one of its key benefits.

Why learn Python?
Programming languages like Python are robust and in demand. Python’s simple syntax makes it an excellent first programming language to learn. Although it has established itself as the standard language of artificial intelligence and data research, Python is widely used in web development, scientific computing, and software development. Python also has a sizable community of contributors that continuously expands its already expansive environment. Python is a fantastic platform, to begin with, for any prospective coder.
Steps involved in creating a Python application
- Setup window
Python 3 must be set up on your system to run the code. If Python 3 is installed on your computer, follow the next steps. By selecting the magnifying glass symbol close to the Start menu, the Search menu will be made available. Enter cmd in the search field. One of the search results will be the Command prompt option. Your screen will launch a quick command window. Type Python and click on Enter at the command prompt. Click the Download Python button on the official Python Downloads website. This will download the installer for the most recent stable Python version to your PC.
- Create first .py file
You can create and execute the first Python program after Python is set up. The .py extension is the default for Python files. You can create, edit, and save Python files with various text editor. Build a file called test.py in the folder where you want to build your first Python file. Next, open this file in a text editor and enter the appropriate code. Before printing anything, the print() command requires a value. Type the command like This is a simple Python application and hit Enter. This is one of the most straightforward applications you can develop in Python.
- Writing a simple function
The def keyword is used before the function name in Python prefaces. A variable is declared inside the function. Depends upon the users program Python’s input function can be used. You call the process with appropriate name as the parameter at the end of the file.
- Creating a table
A file on a disc is where records are kept in the straightforward database SQLite. Although it has less functionality than commercially available database systems like MySQL and PostgreSQL, SQLite is still a more straightforward database to get started with. Most features distinguishing SQLite from other systems relate to complicated data types, performance, and reliability. For production systems, this functionality is proper. Launch the Python interpreter and build a new database to get started using SQLite. Create several rows and columns with the help of the simple SQL syntax.
- Saving the file
It is always a good idea to save your application before launching it. In this manner, your application code is still secure even if a mistake you make results in Python or the system freezing for any reason. It is simpler to return later, figure out what went wrong, fix it, and try running the application again if you saved it. To open the Save As dialogue box, select FileSave. The Edit window automatically selects the Python3 folder to store the application.
Bottom line
If you want to learn more about how to write a Python application, consider enrolling in an online Python certification course, where you will have complete hands-on projects and get valuable career support.
