read file block by block in python












-1














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?

  • You should show whether you have tried anything or not.

  • why are you searching for "MACRO" and "END"? The beginning of a macro must exactly start with "MACRO" and you know it will end when the line starts exactly with "END". No need to search

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)
