Is it possible to develop software code without using an integrated development environment?

Yes, software development is possible without using an integrated development environment (IDE). You can use simple text editors (such as Vim, Nano, Notepad++) to write code, and then run programs through the command line or terminal.

For example, for Python, it is enough to create a file with the .py extension and run it with the command:

python script.py

Although IDEs provide conveniences (debugging, autocomplete, project management), they are not mandatory for development. Many developers prefer lightweight editors or even write code directly in the terminal.
