I have file that has this format

MACRO L20_FDPQ_TV1T8_1

 FIXEDMASK ;

 CLASS CORE ;

 ...

 ...

END L20_FDPQ_TV1T8_1

MACRO INV_20

...

...

END INV_20

I want to read the file as blocks such that each MACRO to end of its name form a block in python. I tried to use this

with open(file_name, "r") as f_read:

    lines = f_read.readlines()

num = 0

while num < len(lines):

    line = lines[num]

    if re.search(r"MACROs+", line, re.IGNORECASE):

            macro_name = line.split()[1]

            while re.search(r"s+ENDs+%s"%macro_name, line, re.IGNORECASE) is None:

                line = lines[num + 1]

                #...do something...

                num = num+1

            num +=1

how this can be done in an efficient way?

Assumming that you cannot nest Macros, that Macros always start with "MACRO [name]" and end with "END [name]":

# read the contents of the file

with open(file_name, "r") as f_read:

    lines = f_read.readlines()



current_macro_lines = 

for line in lines:

    if line.startswith("MACRO"):

        macro_name = line.split()[1]



    # if line starts with END and refers to the current macro name

    elif line.startswith("END") and line.split()[1] == macro_name:

        # here the macro is complete, 

        #put the code you want to execute when you find the end of the macro



        # then when you finish processing the lines, 

        # empty them so you can accumulate the next macro

        current_macro_lines = 



    else:

        # here you can accumulate the macro lines

        current_macro_lines.append(line)
