How do I make a Label in Tkinter Bold ?

This is my code 

labelPryProt=Label(frame1,text="TEXTTEXT")
labelPryProt.pack(side=LEFT,fill=BOTH,expand=False)
labelPryProt.configure(font=("Helvetica",BOLD, 18))#this is not working not making the text as bold

What is the error ?

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')

  • Let's say I allow user to change the text type so how to configure that ? how to change it without declaring the variable again labelPryProt = Label() – zzz123 Sep 29 '17 at 18:48

    Sure, than you'll have to configure it. `labelPryProt.configure(font='Helvetica 18 bold')` – adder Sep 29 '17 at 18:48

    @zzz123: the better solution is to use a font object, so you only have to change it in one place. See http://www.tkdocs.com/tutorial/fonts.html – Bryan Oakley Sep 29 '17 at 19:06
  • This answer is definitely wrong. The question explicitly asks about making a tk Label bold. The answer here is about something else involving the Helvetica font and the font size 18. => -1 – WhyWhat Apr 13 '20 at 19:46

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. :)
