Python Interpreter #

WHAT is this? #

The Python interpreter is usually installed as /usr/local/bin/python3.13 on those machines where it is available.

Since the choice of the directory where the interpreter lives is an installation option, other places are possible; check with your local Python guru or system administrator.

My version: #

We can use which python to find the python interpreter folder location.

WHY is this important? #

My version: #

To translate your Python code for a computer machine (run code).

WHY should i learn this? #

The interpreter is said to be in interactive mode.

WHEN will I need this? #

My version: #

Run Python code interactively.

HOW does this work? #

Start it by typing the command on terminal:

By default, Python source files are treated as encoded in UTF-8. In that encoding, characters of most languages in the world can be used simultaneously in string literals, identifiers and comments — although the standard library only uses ASCII characters for identifiers, a convention that any portable code should follow. To display all these characters properly, your editor must recognize that the file is UTF-8, and it must use a font that supports all the characters in the file.

When known to the interpreter, the script name and additional arguments thereafter are turned into a list of strings and assigned to the argv variable in the sys module. You can access this list by executing import sys. The length of the list is at least one; when no script and no arguments are given, sys.argv[0] is an empty string. When the script name is given as '-' (meaning standard input), sys.argv[0] is set to '-'.
