Re-write the for loop function in python, need help to understand better

Question

I'm new to python and I need help to re-write that for loop function with indentations below

y = [g(x,y) for x in xs for y in xs if f(x,y)]

full code is here

g = lambda x,y:(x-y) 
f = lambda x,y: x>y 
xs = [1,2,3,4] 
y = [g(x,y) for x in xs for y in xs if f(x,y)]

That code is an example, I need a simpler form of for loop to understand so I can visualize. — Reboot

The first can be defined as a function that takes two arguments and returns the difference between the first and second argument. — wwii

y = []
for a in xs:
    for b in xs:
        if f(a, b):
            y.append(g(a, b))
