Python InterpreterA Python interpreter is a program that reads and executes Python code. It is an interactive command-line interface that enables users to write and run Python code in real-time. The interpreter acts as an interface between the user and the Python programming language, allowing users to input Python code and receive output based on the code's execution.
The Python interpreter is responsible for parsing and executing Python code. When a user enters a command, the interpreter reads the code and converts it into a sequence of machine instructions that the computer can understand and execute. The interpreter also provides feedback to the user, such as error messages, as it runs the code.
Python comes with its built-in interpreter, which can be accessed through the command line by typing 'python'. There are also other Python interpreters available, such as IPython, Jupyter, and PyPy, each with its own unique features and capabilities.
