ternary 0.1

Ternary operation implementation

This is a simple hack using the slice operation to mimic C-style ternary operation:

x = a ? b : c

In Python we would write:

>>> x = a and b or c

Or (rather than above, this is safe for returning Falsy values for b):

>>> x = (a and [b] or [c])[0]

Or:

>>> x = b if a else c

Or:

>>> x = lambda i: (b, c)[not a]

Or:

>>> if a:
...     x = b
... else:
...     x = c

Now we can also write:

>>> x = ternary[a:b:c]

Usage

Using the slice operation:

>>> value = ternary[condition:true_result:false_result]
