How to add border to a button in python for Tkinter?

Question

b1 = Button(tk, text=" ", font=("Consolas 30 bold"), height = 1, width = 4,bg = "white", command=lambda:checker(b1))

What piece of code to I add to this to add a border to the button, as in making it thicker?

Solution

as per http://effbot.org/tkinterbook/button.htm:

borderwidth= variable

The width of the button border. The default is platform specific, but is usually 1 or 2 pixels. (borderWidth/BorderWidth)

not to be confused with:

highlightthickness= variable

The width of the highlight border. The default is system specific (usually one or two pixels). (highlightThickness/HighlightThickness)

highlightthickness is not the same as a border, it's more like a ring around the button. A border is controlled with borderwidth and relief.
