How does the initiation and launch of a Python program occur at your workplace?

Initiating and running a Python program usually occurs as follows:

1. A file with the .py extension is created, containing the program code.
2. In the command line or terminal, the Python interpreter is invoked with this file:

python filename.py

3. If a virtual environment is used, it is activated first to use the necessary dependencies.

4. In some cases, the script is run through an IDE (for example, PyCharm), where pressing the run button executes the script.

Example of a simple script hello.py:

print("Hello, world!")

Run:

python hello.py
