Why this code does not draw a window on a python shell?

Question

global winup, win2up

class MyUtils():
def showRoundRect(self,can,x,y,width,heigh,rad):
can.create_arc(x,y+rad*2,x+rad*2,y,start=90, extent=90,style=ARC)

can.create_line(x+rad.y,x+width-rad.y)

can.create_arc (x+width-rad*2,y+rad*2,x+width,y, start=0,extent=90,
style=ARC)
can.create_line(x+width,y+rad,x+width,x+width,y+height-rad)

can.create_arc(x+width-rad*2,y+height,x+width,y+height-rad*2,start=270,extent=90,
style=ARC)

can.create_line(width-rad,y+height,x+rad,y+hieght)

can.create_arc(x,y+height,x+rad*2,y+height-rad*2,start=180, extent=90,style=ARC)

can.create_line(x,y+height-rad,x,y+rad)

def clearRect(self, can,x,y,width,height,rad):
can.create_rectangle(x-2,y-2,x+width+rad+4,
y+height+rad+4,
fill="white",
width=0)
class myButton():

Answer 1

What's that? For the most part, that doesn't even seem to be valid python code. There are several references to unintroduced variables, beginning a code with "global" is rather unusual (is there something missing at the beginning?) and the code just ends in the middle of an arbitrary line

Answer 2

There is from Tkinter import * in the beginning

Answer 3

What I wanted is to make rounded rectangular buttons

Answer 5

Zhenis Otarbay Are you sure that this is python 3 code? I have no idea about python 2, but in python 3 it doesn't really make sense to begin a code with the "global" keyword. To me it looks like a failed attempt at declaring a global variable, which is not the way things work in python 3. If I remember correctly, the name of the module is Tkinter in python 2 and tkinter (not capitalized) in python 3 so that would make sense
