Conditionals Nested Loops in List Comprehension

Question

How to compress this whole loop into one single line. Is there any way?

aa = []  
for x in args:
   for y in args:
     if x == y:
       pass
     else:
       kk = x*y
       aa.append(kk)

from itertools import product
aa = [x*y for x,y in product(args, args) if x != y]

Absolutely nothing wrong with previous answer. A double loop also works and might be a little simpler to understand.

[x * y for x in args for y in args if x != y]

``` total = 0 for x in args: total = total + x total2= 2*total ``` can this be compred in one line @Frank Yellin – zircon Sep 15 '20 at 08:31
