Tcl (pronounced “tickle” or as an initialism) is a high-level, general-purpose, interpreted, dynamic programming language.

It was designed with the goal of being very simple but powerful.

Tcl casts everything into the mold of a command, even programming constructs like variable assignment and procedure definition.

Tcl supports multiple programming paradigms, including object-oriented, imperative, functional, and procedural styles.

It is commonly used embedded into C applications, for rapid prototyping, scripted applications, GUIs, and testing.

Tcl interpreters are available for many operating systems, allowing Tcl code to run on a wide variety of systems.

Because Tcl is a very compact language, it is used on embedded systems platforms, both in its full form and in several other small-footprint versions.The popular combination of Tcl with the Tk extension is referred to as Tcl/Tk (pronounced “tickle teak” or as an initialism) and enables building a graphical user interface (GUI) natively in Tcl.

Tcl/Tk is included in the standard Python installation in the form of Tkinter.
