4.4. Match Pattern WildcardΒΆ
The wildcard pattern is a single underscore: _
. It always
matches, but does not capture any variable (which prevents
interference with other uses for _
and allows for some
optimizations).
>>> def html_color(name):
... match name:
... case 'red': return '#ff0000'
... case 'green': return '#00ff00'
... case 'blue': return '#0000ff'
... case _: raise NotImplementedError
