iconbitmap () the parameter required is the address of the icon.

if your python.ico files are placed in the current directory, it's OK to directly root.iconbitmap ('python.ico') .
if the python.ico files are placed in another directory, such as / home/user/foo/python.ico , use the absolute path, root.iconbitmap (' / home/user/foo/python.ico') .

in short, make sure that the python.ico file exists in your file path.
