You can use regular expressions module like this. 

>>> import re
>>> match_upto_brackets = re.compile(r'.*[>\]}](.*)')
>>> match_upto_brackets.sub(r'\1', '<values> 4 50').strip()
'4 50'
>>> match_upto_brackets.sub(r'\1', '<values] 7 400').strip()
'7 400'
>>> match_upto_brackets.sub(r'\1', '<values} 9 70').strip()
'9 70'
>>>
