Make a Label Bold Tkinter

You have to put bold in quotes, like this: label = Label(frame1, text='Hello', font=('Helvetica', 18, 'bold')) . This method works for me.

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. :)

You don't have to configure it separately, you can pass an argument when you are creating the widget:

labelPryProt = Label(frame1, text='TEXTTEXT', font='Helvetica 18 bold')
