There is little to gain with such a small expression but using a function just to not having to repeat the summation and comparison could be an option. It makes it a bit more maintainable when wanting...

As an old habit of my programming, I think placing complex expression at right in a clause can make it more readable like this:a == b+c or b == a+c or c == a+bPlus ():((a == b+c) or (b == a+c) or (c ==...

Don't try and simplify it. Instead, name what you're doing with a function:def any_two_sum_to_third(a, b, c): return a + b == c or a + c == b or b + c == aif any_two_sum_to_third(foo, bar, baz):...

Python 3:(a+b+c)/2 in (a,b,c)(a+b+c+d)/2 in (a,b,c,d)...It scales to any number of variables:arr = [a,b,c,d,...]sum(arr)/2 in arrHowever, in general I agree that unless you have more than three...

How about just:a == b + c or abs(a) == abs(b - c)Note that this won't work if variables are unsigned.From the viewpoint of code optimization (at least on x86 platform) this seems to be the most...

The solution provided by Alex Varga "a in (b+c, b-c, c-b)" is compact and mathematically beautiful, but I wouldn't actually write code that way because the next developer coming along would not...

(a+b-c)*(a+c-b)*(b+c-a) == 0If the sum of any two terms is equal to the third term, then one of the factors will be zero, making the entire product zero.

Python has an any function that does an or on all the elements of a sequence. Here I've converted your statement into a 3-element tuple.any((a + b == c, a + c == b, b + c == a))Note that or is short...

Is there a more compact or pythonic way to write the boolean expressiona + b == c or a + c == b or b + c == aI came up with a + b + c in (2*a, 2*b, 2*c)but that is a little strange.
