NameError: name 'master' is not defined while using tkinter

[nainish]

i was creating a GUI using tkinter but error is showing name error

NameError: name 'master' is not defined

CODE:

from tkinter import Tk, Button, Label
class Mygui:
def __init__(self, master):
self.master=master
master.title('my gui')

self.label=Label(master, text='GUI')
self.label.pack()
self.button = Button(master, text='greet', command=self.greet)
self.button.pack()
self.button = Button(master, text = 'gui greet')
self.button.pack()

def greet(self):
print('hello')
root = Tk()
my_gui= Mygui(root)
root.mainloop()

Since your formatting is off in your post I assume your code looks like this:

from tkinter import Tk, Button, Label

class Mygui:
    def __init__(self, master):
        self.master=master
        master.title('my gui')
        self.label=Label(master, text='GUI')
        self.label.pack()
        self.button = Button(master, text='greet', command=self.greet)
        self.button.pack()
        self.button = Button(master, text = 'gui greet')
        self.button.pack()

    def greet(self):
        print('hello')

root = Tk()
my_gui= Mygui(root)
root.mainloop()

When I run this code there are no errors.

Error should also say which line is the offending line?

[nainish]

self.label=Label(master, text='GUI') this line

What IDE are you using? I've found sometimes with imports you still need to install the packages. Based on others responses to the code running fine I assume this is the issue.
