In ?Tcl, a widget is created by invoking the widget command with the name of the new widget and any configuration parameters. In Python, a widget is created by calling the class with the name of the new widget's parent and any configuration parameters. "-name value" pairs in Tcl become "name=value" keyword arguments in Python
| Tcl | Python |
| button .t.b -text "Click Me" | b = Button(t, text="click me") |
Widgets have methods which may accept positional or keyword arguments. Many methods are shared by all widget types, while almost every widget has a few special methods.
| Tcl | Python |
| .t.b invoke | b.invoke() |
| .t.e insert end {Sample Text} | e.inert("end", "Sample Text") |
Some widget methods have compound names, which are typically spelled with an underscore in Python and a space in Tcl
| Tcl | Python |
| .t.t tag add newtag 0.0 end | tt.tag_add("newtag", 0.0, "end") |
Some methods in Python are separate commands in Tcl:
| Tcl | Python |
| grid .t.b | b.grid() |
When a keyword or name in Tcl is a Python reserved word, append a "_" when using it as a keyword argument:
| Tcl | Python |
| grid .t.b -in .t.f | b.grid(in_=f) |
Some special values used in Tcl are defined as constants in Tkinter:
| Tcl | Python |
| pack .b -side left | b.pack(side=Tkinter.LEFT) |
| b.pack(side="left") |
