如何使我的特殊直角三角形程序工作？

Question

Write a program in python to list the special trianglesperimeters of which are less than 500 (no user input).

I tried writing this but it didn't seem to work.

from math import sqrt

natural_to_500_a = 1
natural_to_500_b = 1

while natural_to_500_a <= 499 and natural_to_500_b <= 499:
    natural_to_500_a += 1
    natural_to_500_b += 1

    h_side = sqrt(natural_to_500_a**2 + natural_to_500_b**2)

    print(h_side)

edit: i wrote this code it gave me the same wrong answers again

from math import sqrt

for a in range(0, 501):
    c = sqrt(a**2 + a**2)
    print(c)

Answer 1

There are better ways to compute Pythagorean triples, but this is simple:

for a in range(1,500):
    for b in range(1,500-a):
        for c in range(1,500-a-b):
            if a**2+b**2 == c**2:
                print(a,b,c)

Note that the ranges ensure that the perimeter is less than 500.
