Make a Label Bold Tkinter
Just put bold in the quotes, example : label = Label(frame1, text = "TEXTTEXT", font = ('Helvetica', 18, 'bold'))
That work for me, configure also work but you have to make one more line of code.If you want, I can show you how to .configure
:Just add this code : label.configure(font=("Helvetica","bold", 18))
Thanks. :)
