Help with re.search function

Question

I have a for who plays at a dictionary to check what the user typed to see is the same, to call a function... the case at issue:

FOR

for x in abrir:
                if(re.search(abrir[x], user_response, re.IGNORECASE)):
                    print(abrir_coisas(user_response)) 

(if there’s a way to do it in an if I’d appreciate it too, but that’s not my question right now)

In the dictionary in question I have it:

abrir = {....26:'\\babrir notepad\\b', 27:'\\babra notepad\\b',...60:'\\b\\wabrir notepad\+\+', 61:'\\b\\wabra notepad\+\+'... 

Who in turn plays for it in function:

elif ((re.search('\\babrir notepad\\b', user_response, re.IGNORECASE)) or (re.search('\\babra notepad\\b', user_response, re.IGNORECASE))):
                if file == "notepad.exe":

and this

elif ((re.search('\\b\\wabrir notepad\+\+', user_response, re.IGNORECASE)) or (re.search('\\b\\wabra notepad\+\+', user_response, re.IGNORECASE))):
                if file == "notepad++.exe":

Except that it is ALWAYS opening NOTEPAD and not NOTEPAD++ no matter what I do, could anyone help me solve this? I imagine I’m forgetting to use some simple code, only I’m not getting it. Thank you.
