Python match case

x = 4

# x is the variable to match
match x:

    # if x is 0
    case 0:
        print("x is zero")

    # case with if-condition
    case 4 if x % 2 == 0:
        print("x % 2 == 0 and case is 4")

    # Empty case with if-condition
    case _ if x < 10:
        print("x is < 10")

    # default case(will only be matched if the above cases were not matched)
    # so it is basically just an else:
    case _:
        print(x)



# WHAT THE CODE WOULD LOOK LIKE IF IT DIDN'T USE MATCH/CASE

x = 4

if x == 0:
	print("x is zero")
elif x == 4 and x % 2 == 0:
	print("x % 2 == 0 and case is 4")
elif x < 10:
	print("x is < 10")
else:
	print(x)
