The difference beetween the number of bytes is due to the fact that vyxal and python doesn't use the same charset

Explanation :

• Vyxal

a=" # do nothing revelent here
 `q‛:Ė+ `:Ė # structure for a quine
 34Cp‛a=p # prepend `a="` to the string 
 rint # do stuff that somehow push 0 to the stack
 ( ) # for loop over 0 (do nothing)
 # # comment and implicily close the loop
 # implicit output

• Python

The quine is a variation of a="print('a=%r;exec(a)'%a)";exec(a)
