python3: The Python programming language

Description

By default, Sage will try to use system’s python3 to set up a virtual environment, a.k.a. venv rather than building a Python 3 installation from scratch.

Sage will accept versions 3.8.x to 3.10.x.

You can also use --with-python=/path/to/python3_binary to tell Sage to use /path/to/python3_binary to set up the venv. Note that setting up the venv requires a number of Python modules to be available within the Python in question. Currently, as of Sage 9.7, these modules are as follows: sqlite3, ctypes, math, hashlib, crypt, socket, zlib, distutils.core, ssl - they will be checked for by the configure script.

Use the configure option --without-system-python3 in case you want Python 3 built from scratch.
