SageMath, the Sage Mathematical Software System: free software for Computational Mathematics, based on Python. See longer description for links to other similar-sounding tags.

SageMath

SageMath, formerly SAGE, then Sage, is computational mathematics free software. It includes

python as the user language, also used in a lot of the source code
maxima, sympy, ginac (via Pynac) for symbolic algebra
numpy, scipy can be used for numerical computations
jupyter-notebook for its notebook system, with its own jupyter-kernel
SageTex to embed results into latex documents
many more components, in various languages, but interfaced in Python for usage in Sage

SageMath uses the Python language, with a tiny bit of syntactic sugar to ease definition of mathematical objects such as symbolic functions, number fields, polynomial rings. Some parts are written in cython or C/C++ for speed, but a typical user would only use Python syntax. Python wrappers help call other software included in SageMath pythonically.

It is possible to use SageMath using texmacs.

Similar-sounding but unrelated tags

Many other things are called Sage. Please use the appropriate tags.

Use sage-one, sage-line-50, sage50, sage-300, sagepay, sage-crm, sage-erp for various accounting and business management software by The Sage Group PLC.
Use roots-sage for the WordPress starter theme by roots.io.
Use amazon-sagemaker for Amazon SageMaker, a machine learning service by Amazon.
Use sageframe for SageFrame, a "content management system" (CMS) on top of ASP.NET

Only use the sage tag for questions about SageMath, the Sage mathematics software system.

The TeX.SE website has a [sagetex] tag for SageTeX questions.

MathOverflow also has a [sage] tag for Sage questions.

Note also that Ask Sage, SageMath's questions-and-answers site, and sage-support, the user support mailing list, are very active and that questions asked there typically get answered faster than on the StackExchange network.
