Regex Python Error

I'm tring to find <20> UNIQUE Registered in hostname <20> UNIQUE Registered and replace it with "" in python. Below is my code. Please inform me where my syntax is wrong to replace this string:

string = string.replace(r'<\d*2>  UNIQUE      Registered ', "")

replace() cannot do regular expression substitution. Use re.sub() instead:

>>> import re
>>> s = "hostname <20>  UNIQUE      Registered"
>>> re.sub(r"<\d{2}>\s+UNIQUE\s+Registered", "", s)
'hostname '

where \d{2} would match 2 subsequent digits, \s+ - one or more space characters.

As a side note, could not you just split the string by space and get the first item:

>>> s.split()[0]
'hostname'
