Hi, James,
You might prefer:
d = {'name': 'James', 'language': 'English'}
value = d.get('sex', 'unknown')
This accomplishes what your above code does, using a method of the
built-in dict object.
If you also wish to ADD the new value to the dictionary, you may also
use the following:
value = d.setdefault('sex', 'unknown')
This returns the same value as the above, but also adds the key 'sex' to
the dictionary as a side-effect, with value 'unknown'.
Cheers,
-M
