How to get the complete string value while searching a partial string in a file through python?

I have a file which contains the below logs. Now I want to find out where my TD_Map string is. I can achieve that through str.find() method. But is there a way to get the complete string as a return value? Like for this example I must get TD_Map2. I have to search TD_Map string only because the rest part can be any integer constant. 

Running  
OK, start the cluster assignment.  
: 6035
Warning: The Default Cluster size results in a cluster with multiple Amps on the same Clique.  
The cluster assignment is complete.  
Reading  
da 6-7
Running    
OK.  
The AMPs 6 to 7 are deleted.>  
Reading  
ec   
Running  
OK.  
The session terminated. TD_Map2 is saved.>

There are so many ways to do this, but it seems like a nice use case for regex:

import re

s = """Running  
OK, start the cluster assignment.  
: 6035
Warning: The Default Cluster size results in a cluster with multiple Amps on the same Clique.  
The cluster assignment is complete.  
Reading  
da 6-7
Running    
OK.  
The AMPs 6 to 7 are deleted.>  
Reading  
ec   
Running  
OK.  
The session terminated. TD_Map22 is saved.>
"""

match = re.search('TD_Map([\d]+)', s)
print(match.group(0))  # Print whole "TD_Map2"
print(match.group(1))  # Print only the number "2"

Output:

TD_Map2
2
