python - I can't find a simple filter for my pyth triples filter -

i want filter down primitive triples ([3,4,5], [7,24,25], etc.) nothing non-primitive [6,8,10] , can't seem figure out, in code took out attempts @ filter, , displays primitive , non-primitive triples.

import tkinter import sys fractions import gcd   def func(event):     x = int(e1.get())  # max number     result = []     in range(1, x):  # loops each value in range of x         b in range(a, x):             c in range(b, x):                 if a**2 + b**2 == c**2 , gcd(a, b) == 1:  # if primitive pyth triple, append result                     result += ['[',a,',',b,',',c,']']  # add group of triples list     l = tkinter.message(root, text=result).grid(ipadx=5, ipady=5, sticky='w''e')  # display each group of triples root     l0 = tkinter.label(root, text="non-primitive , primitive triples").grid(ipadx=5, ipady=5, sticky='w''e')     root.bind('<return>', close)  # hit enter exit, temp debugging, reassign button later   def close(event):  # close program, define parameter event allow binding     tkinter.sys.exit(0)     sys.exit(0)   root = tkinter.tk()  # establish main gui root.title('generator') e1 = tkinter.entry(root) assert isinstance(e1, object)  # method i've found allow entry().grid() e1.grid(ipadx=5, ipady=5, sticky='w''e') root.bind('<return>', func)  # bind enter, cleaner , quicker button root.mainloop() 

import gcd (from fractions import gcd) , add test line check if triple pythagorean this:

if a**2 + b**2 == c**2 , gcd(a, b) == 1:

that should produce primitive triples.
