Can you describe the sequence of program code execution in interpreted languages?

In interpreted programming languages, code is executed line by line or block by block without prior compilation into machine code. The execution sequence typically is:

1. The interpreter reads the source code.
2. The code is tokenized and syntactically analyzed.
3. Commands are executed directly — instructions are processed one after another.
4. Built-in functions or modules are called if necessary.

For example, in Python, code is executed from top to bottom, line by line, and the program structure can be dynamically changed during execution.
