``` import math

def perf(): counter = 0 for i in range(1,100): for j in range(1,100): k = i2 + j2 k = math.sqrt(k)

        if k.is_integer():
            #print(f"{i} and {int(k)}, are perfect triangles")
            counter += 1
print(counter)

perf() ```

iterate through a string with numbers for 3 loops and then iterate through a string of numbers for 4 loops, that will give every iteration
