Python Convert sequence of string numbers to list of integers

Question

I have a sequence of numbers such as 1-3-6-16-20 I need to be able to convert these to a list of numbers such as [1,3,6,16,20]

I've tried to make a regex to substitute the hypen to a comma and add in the square brackets around it, but it doesn't work

def stringToInt(value):
    reformat = re.sub(r'\-', r',', value)
    reformat = [reformat]
    return reformat

It gives me ['1,3,6,16,20']
