This is a follow up from my kata Insert Dashes. 
Write a function ```insertDashII(num)``` that will insert dashes ('-') between each two odd numbers and asterisk ('\*') between each even numbers in ```num``` 
For example: 
```insertDashII(454793)``` --> 4547-9-3  
```insertDashII(1012356895)``` --> 10123-56*89-5 

Zero shouldn't be considered even or odd.

Difficulty: EASY
Starter code: def insert_dash2(num):
	

Solutions:
def insert_dash2(num):
	prev = 0
	out = ''
	for dig in str(num):
		if int(dig) % 2 == int(prev) % 2 and int(prev) and int(dig):
			out += '*-'[int(prev) % 2]
		out += dig
		prev = dig
	return out
