I changed your first line to
icon = 'test.ico'

and had test.ico in current dir, and it works fine.

a damaged .ico file or it doesn't exist,
or maybe it has something to do with your IDE
which I have never used (I'm still happily using IDLE),
or something to do with your OS, I'm using windows 7.

None of these seems likely though, so I'm sorry, I'm stumped, bro.
I did a write up on this as a code snippet where you can
download some icons and test code, maybe this is worth a look to you?
See the second code snippet 52-Change Tk Window Icon

from tkinter import filedialog, Tk

root = Tk()

#Open file dialog
file_selected = filedialog.askopenfilename(filetypes=[('ico files','*.ico')])

root.minsize(300, 200)
root.title("My Window")
root.iconbitmap(file_selected)
 
root.mainloop()

This will run a file selector so you can manually choose
any .ico file from anywhere and it will use that icon.

from tkinter import filedialog, Tk

root = Tk()

#Open file dialog
file_selected = filedialog.askopenfilename(filetypes=[('ico files','*.ico')])

root.minsize(300, 200)
root.title("My Window")
root.iconbitmap(file_selected)
 
root.mainloop()
