extract text from regular expression

I am new with regular expressions. I want to extract timestamp value from this text

chunk =['leaset loaded server= 10, timestamp= 1494370749.94']
try:
     found = re.findall('\['+'+ timestamp= +'+'\]', chunk).group(1)
  except AttributeError:

     found = 'Not found'

this gave me not found. what is the correct statement for extracting it.

You seem to be mixing up findall and search. While you could write it either way, search will stop after it finds the string and so its a bit faster. 

>>> import re
>>> chunk = 'leaset loaded server= 10, timestamp= 1494370749.94'
>>> match = re.search(r'timestamp= ([\d\.]+)', chunk)
>>> if match:
...     print(match.group(1))
... 
1494370749.94
