Regex expression issue

Question

Hi!
I'm trying to create a regex expression for the following string:

#define AC0_BAP_NR_START
#define AC0_BAP_NR_DS_START

for match only the first expression. I find this pattern - > (. *) #define AC([0-3] )_BAP_(.*)_START but it's matched the both of the strings. Unfortunately, I didn't find the right expression to exclude the DS for the pattern and I need some help from you, guys. I know I may ask too much but it's really annoying me.

I apreciate your help!

Answer 1

Didn't test it but try this:
/#define AC[0-3]_BAP_([A-Z]{2})_([A-Z]{2}_)?START/

just read the question again and if I understood well, you don't want the second line to match. Then you could try

#define AC[0-3]_BAP_([A-Z]{2})_START

Answer 2

Does this work?
m = re.match(r".*#define\s*AC[0-3]_BAP_\w{2}_START", t1)
print(m)
