What isn't working? Why

1. Provided the remainder of the pattern is greedy and it will be used
only for findall, the \b seems pointless.
2. What is the "|" for? Inside a character class, | has n
My quick attempt is below:
obj = re.compile(r'\b[0-9|a-zA-Z]+[\w-]+')
>>> re.findall(obj, 'TestThis;1234;Test123AB-x')
['TestThis', '1234', 'Test123AB-x']
This is not working.
Requirements:
The text must contain a combination of numbers, alphabets and hyphen
with at least two of the three eleme
