从多行字符串的第一行读取

Question

I have a directory with files as:

ab_list
bd_list
cd_list
mno_list
hk_list 
pd_list

I have another file called testfile as outside this directory as:

abc
que nw

ab_list   ON   8
gs_list   ON   9
hk_list   OFF  9
bd_list   ON   7
cd_list   OFF  6
fr_list   ON   5
mno_list  ON   4
pq_list   OFF   6
jk_list   ON   7
pd_list   OFF  8

I want to compare the 2 and all the files with filename and ON next to it(if matched) their content should get merged into a new file called merge_file. The other files which match with testfile but have OFF, their filenames should be printed in a new_file. contents of ab_list bd_list and mno_list should get merged into top_file

here is the code I have tried till now:

from glob import glob

test_file_directory = "C:\\Users\\User\\Desktop\\Folder\\"

files1 = glob("*.txt")
with open(test_file_directory+"testfile.txt","r") as f:
    files2 = [' '.join([l.split()[0],l.split()[1]]) for l in f.readlines()[3:]]

for f1 in files1:
    for f2 in files2:
        if f1[:-4]+'   ON' == f2:
            #print('match')
            with open('merge_file.txt','a') as a:
                with open(f1,'r') as r:
                    a.write(r.readlines()[1:]+'\n')
        elif f1[:-4]+'   OFF' == f2:
            #print('match')
            with open('match_file.txt','a') as a:
                with open(f1,'r') as r:
                    a.write(f"{f2} {len(r.readlines())}\n")
elif f1[:-4]+'   ON' == f2:
            #print('match')
            with open('match_file.txt','a') as a:
                with open(f1,'r') as r:
                    a.write(f"{f2} {len(r.readlines())}\n")

I want that the file contents being written in merge_file start being read from second line of file instead of first and match_file also has the filenames with ON next to it(it has OFF from the first elif) a.write(r.readlines()[1:]+'\n' this line gives an error saying it is a string and not a list.

Answer 1

a.write(r.readlines()[1:]+'\n')

It perform an add with r.readlines()[1:] and '\n'.

r.readlines()[1:] is a list with each line in file.

So you got error

TypeError: can only concatenate list (not "str") to list

What you should do is to join all line in list with '\n' by using join, like

a.write('\n'.join(r.readlines()[1:])+'\n')

Anyway, to copy content of file, you should use f.read(), not f.readlines()

a.write(r.read()+'\n')

To get ride first line, you can use str.partition('\n'), it divide source string to three partitions as [first_string, '\n', next_string], like

a.write(r.read().partition('\n')[2]+'\n')
