With a dict like so:
cond = {'a': 1, 'b': 1, 'c': 1,
'A': 0, 'B', 0, 'C':0}
how would you make a boolean expression like this:
bool = (('a' == 1) & ('A' == 0) |
('b' == 1) & ('B' == 0) |
('c' == 1) & ('C' == 0))
The fact that lowercase and uppercase keys are stringed together with & is
intentional albeit the actual condition is a bit more tricky.
I've tried several approaches using eval() on a string built from the dict
but landed with just spelling it out literally.
Any pointers welcome.
