Python regex find match words by AND conditio

    def count_conditions(input_str, listbox):
        electric_attributes = ['electric', 'batter', "power"]
        input_str = input_str.strip().replace('\r\n', '\n').replace('\r', '\n')
        pattern = re.compile(r'(\{AND.*?\})', re.DOTALL)
        matches = re.findall(pattern, input_str)
        
        line_num = 1

        for match in matches:
            attrs_found = []
            words = re.findall(r'\b\w+\b', match)
            for word in words:
                for attr in electric_attributes:
                    if attr in word.lower() and word not in attrs_found:
                        attrs_found.append(word)
                        
                        
            if attrs_found:
                message = "{} electrical attribute(s) found on lines {}-{} of AND condition: {}".format(
                    len(attrs_found), 
                    line_num, 
                    line_num + len(match.splitlines()) - 1, 
                    ', '.join(attrs_found)
                )
                
            else:
                message = "No electrical attribute(s) found on lines {}-{} of AND condition".format( 
                    line_num, 
                    line_num + len(match.splitlines()) - 1, 
                )
            listbox.insert("end", message)
            line_num += match.count('\n') + 1

I want the code to be able to determine the external "and" syntaxes, and not those that are already inside AND syntaxes.

For example lines 1-14 should be treated as 1 AND syntax, not 3.

{AND
condition_1:batterie
condition_2:samsung
{OR
{AND
condition_1:TV
condition_2:LCD
}
{AND
condition_1:remote
condition_2:TV
}
}
}

{AND
condition_1:batterie
condition_2:samsung
{OR
condition_3:TV
condition_4:remote
}
}

The Output should be:

1 electrical attribute found on lines: 1-14 of AND condition: batterie
1 electric attribute found on lines 15-22 of AND condition: batterie.

Please help! What am I doing wrong?
Or maybe other approach?

I wrote some code based on my comment (I made some changes to yours too, printing the lines instead of inserting them in the unknown listbox object and updating electric_attributes with the full name of batterie).

def count_conditions(input_str):
electric_attributes = ['electric', 'batterie', "power"]
input_lines = 

open_brackets = 0
for i, line in enumerate(input_lines):
if open_brackets == 0:
# Start of a new outer 'AND' block
if '{AND' in line:
open_brackets = line.count('{')
current_block = line
block_start = i + 1
continue
else: 
# this shouldn't actually happen! But if it does, ignore the line
continue
current_block += line
if '{' in line:
open_brackets += line.count('{')
if '}' in line:
open_brackets -= line.count('}')
if open_brackets == 0:   
# We've reached the end of the current external 'AND' block
attrs_found = [attr for attr in electric_attributes if attr in current_block]
if attrs_found:
l = len(attrs_found)
print(f'{l} electrical attribute{"s" if l > 1 else ""} found on lines {block_start}-{i + 1}'
f' of AND condition: {" ,".join(attrs_found)}')
else:
print(f'No electrical attribute found on lines {block_start}-{i + 1}'
f' of AND condition')
