According to TIOBE Python has overtaken Java and is most likely to overtake C in the near future. Python is the most searched language according to PYPL Index. There are some advantages to using Python for this popularity. Here are some advantages:
- Python is easy to read, learn and write.
- Improved productivity due to its simplicity.
- Effectively executes the code sequentially line by line which can make it easier to debug than event-driven code.
- Automatically assigns the data type during execution.
- Free and Open-Source.
- Huge standard library of read-made functions and features.
- Code once and run on many platforms.
In this article, you’ll learn why a typical Python program is so short, how to run Python scripts using the Python Windows GUI Builder, and more about demo applications that use Python in Delphi programs. You can also find out more about building Python GUI apps.
Why is the source code of a typical Python program so short?
This brevity comes about because Python has a huge standard library allowing many activities and functionality to be expressed with smaller and more succinct program statements compared to many other languages. There is a test in Github to prove this code-brevity hypothesis. It is called Raytracer benchmarks and it’s based on examples from Typescript. Python got second place with just 275 lines of code. You can check that here.
How can I run Python scripts in Delphi?
It’s great if we can take the advantage of Python’s advantages in our Delphi application, combing the best of both worlds. Let’s see how we can run a Python script inside a Delphi application. The easiest way to do that is by using Python for Delphi (P4D). Python for Delphi (P4D) is an open-source project by pyscripter. You can find the source code of Python for Delphi (P4D) from this link.
You can clone the source and install components by using the packages in the packages folder. Then add the source path to the library and you are ready to go.
Are there any demo applications of using Python in Delphi programs?
There are many Demo applications you can run out of the box. There are two components we use often.
TPythonEngine: We use this component to execute Python scripts.
TPythonGUIInputOutput: We use this component to get output to a UI component (Eg: TMemo).
By using those components, we can execute a Python script and get the result with just a single line of code.
procedure TForm1.Button1Click(Sender: TObject);
PythonEngine1.ExecStrings( Memo1.Lines );
You can run the Demo projects and get results from a Python script at runtime.
Did you know you can run Python programs with Delphi? These two languages combined together make a remarkably comprehensive solution to almost any software problem you can imagine.
