Example
Evaluates to the first truthy argument if either one of the arguments is truthy. If both arguments are falsey, evaluates to the second argument.
x = True
y = True
z = x or y # z = True
x = True
y = False
z = x or y # z = True
x = False
y = True
z = x or y # z = True
x = False
y = False
z = x or y # z = False
x = 1
y = 1
z = x or y # z = x, so z = 1, see `and` and `or` are not guaranteed to be a boolean
x = 1
y = 0
z = x or y # z = x, so z = 1 (see above)
x = 0
y = 1
z = x or y # z = y, so z = 1 (see above)
x = 0
y = 0
z = x or y # z = y, so z = 0 (see above)
The 1's in the above example can be changed to any truthy value, and the 0's can be changed to any falsey value.
