Python and Tcl
|
|
Tcl on the surface looks a lot like Python. Both languages can be used to write elegant, simple code. Tcl is primarily a string processing language. The only datatypes in Tcl are strings and one-dimensional arrays of strings.
Python, in contrast, comes with a full range of data types including numbers (integers, long integers, floating point, octal, hex, and complex numbers), strings, lists, dictionaries (arrays indexed by keys, like hashes in Perl), and tuples (simple lists that can't be changed in place).
Tcl and Python share the same GUI toolkit, Tk. Python's interface to Tk is called Tkinter, and it is included with all recent versions of Python. You are not limited to using just Tk to build GUIs in Python, however. You can also use the Gimp Tool Kit (GTK) and Gnome extensions to GTK+.
