Unless Python
Short post! You can still read, unless you’re in a hurry.
>>> unless = lambda condition: condition is not True
>>> breakfast_is_ready = False
>>> if unless(breakfast_is_ready):
... print("Sleeping...")
... else:
... print("Getting up!")
...
Sleeping...
>>> breakfast_is_ready = True
>>> if unless(breakfast_is_ready):
... print("Sleeping...")
... else:
... print("Getting up!")
...
Getting up!
Here is Ruby/Perl’s unless conditional in Python. It’s basically a fancy “if not”.
