Giovanni Lombardo <[email protected]> added the comment:
I propose the below fix:
```
def unbind(self, sequence, funcid=None):
"""Unbind for this widget for event SEQUENCE the
function identified with FUNCID."""
bound = ''
if funcid:
self.deletecommand(funcid)
funcs = self.tk.call('bind', self._w, sequence, None).split('\n')
bound = '\n'.join([f for f in funcs if not f.startswith('if
{{"[{0}'.format(funcid))])
self.tk.call('bind', self._w, sequence, bound)
```
