A Pythagorean triplet is a set of three natural numbers, $a < b < c$, for which,$$a^2 + b^2 = c^2$$
For example, $3^2 + 4^2 = 9 + 16 = 25 = 5^2$.
There exists exactly one Pythagorean triplet for which $a + b + c = 1000$. Find the product abc.
I first created two lists, A and B, and set them to all values up to 1000.
In :A = range(1000) B = range(1000)
Using two for loops, I looped through all the values in A, then all the values in B. Using the formulas for pythagorean triples from the wikipedia page about them, I used an if statement that said if the value in B was larger than the value in A, then to define three variables by their respective formula. These would be my pythagorean triples. Finally, I created another if statement that compared whether the sum of the pythagorean triples was 1000. If the sum was 1000, I printed the product.
In :for n in A: for m in B: if m > n: a = m ** 2 - n ** 2 b = 2 * m * n c = m ** 2 + n ** 2 if a + b + c == 1000: print(a * b * c)
