Generating unique, ordered Pythagorean triplets

Question

This is a program I wrote to calculate Pythagorean triplets. When I run the program it prints each set of triplets twice because of the if statement. Is there any way I can

Answer 1

# To find all pythagorean triplets in a range
import math
n = int(input('Enter the upper range of limit'))
for i in range(n+1):
    for j in range(1, i):
        k = math.sqrt(i*i + j*j)
        if k % 1 == 0 and k in range(n+1):
            print(i,j,int(k))
