How to print from all line in between two pattern - kttan - Feb-07-2019
Sorry im totally new in python, if can have some explanation on code, and try split in few function, so i can more easily learn and apply at other place.
i'm try search net but unable to find this function, most of them can't extract exactly same , and can't extract out the line with ;.
Im have 2 file , file_A and file_B.
Have few condition.
1. Need exactly same only will extract out. exp(will only extract "+5VIN" pattern only , and "+5VIN_2" won't.)
2. extract all until found ";", include the line.
3. the output file will ignore "."
4. will remove duplicate.
file_A
#
+5VIN
2FS_ECL0
#
file_B
#
+5VIN
TP94.1
R1.2
U43.30;
+5VIN_2
TP95.1
U43.32;
2FS_ECL0
TP94.2
R100.1;
#
expected output file:
#
TP94
R1
U43
R100

below is the code im try, but it unable to work, and it only hardcode , unable to get string from the other list.
Board_file = open("board","r")
Board_connection = open("Board_filter1","w")
def Board_File_filter1():
Beginning = "+5VIN"
Ending = ";"
print_swt = 0
with Board_file as f:
for line in f:
if Beginning in line:
print_swt = 1
if Ending in line:
print_swt = 0
if print_swt:
X = line
Board_connection.write(str(X))

i'm have try below code:
def Extract_part1():
for Beginning in search_words:
infile = open("File_B","r")
outfile = open("Output_file","w")
print_swt = 0
with infile as f:
for line in f:
if Beginning in line:
print_swt = 1
if ";" in line:
print_swt = 0
if print_swt:
X = line
outfile.write(str(X))
print(print_swt)
infile.close()
outfile.close()
rmv_list = open("file_A")
search_words = []
for word in rmv_list:
search_words.append(word.strip())
rmv_list.close() the output file i get is(highlight in red only:+Output:+5VIN
TP94.1
R1.2

rmv_list = open("file_A")
search_words = []
for word in rmv_list:
search_words.append(word.strip())
rmv_list.close()

Sorry, but these conditions don't make sense to me. If you cant articulate what are the exact conditions then it's near to impossible to help.
