$3-(20$ marks$)$ Given two variables a and b$,$ write a Python code snippet to perform the following operations in the same order: If a is greater than b and a is even, print $"$a is greater than b and a is even". If a is less than b and b is odd, print $"$a is less than b and b is odd". If a is equal to b$,$ print $"$a is equal to b$".$ If none of the previous comparisons are true print "None of them matched"$\mathrm{.}4-$
