python - Write from Text files to CSV Files -

i trying write rows contain string: bunch of text files. code:

import os import glob import csv import re  #defining keyword keyword = '2012-07-02'  #code merge relevant log files 1 file , insert  open('combined-01022012.txt' , 'w', newline = '') combined_file:     csv_output = csv.writer(combined_file)     filename in glob.glob('fao_agg_2012_part_*.txt'):         open(filename, 'rt', newline = '') f_input:         #with gzip.open((filename.split('.')[0]) + '.gz', 'rt', newline='') f_input:             csv_input = csv.reader(f_input)             row in csv_input:                 row.insert(0, os.path.basename(filename))                 try:                     if keyword in row[2]:                         csv_output.writerow(row)                 #row.insert(0, os.path.basename(filename))                 #csv_output.writerow(row)                 except:                     continue             continue 

everything seems right , code runs nothing gets written on text file. going wrong?

your main problem in lines:

row.insert(0, os.path.basename(filename)) try:     if keyword in row[0]:         csv_output.writerow(row) except:     continue 

you're inserting parent folder name of current file first entry of row, , on next line you're checking if entry (row[0]) contains keyword. unless parent folder contains keyword (2012-07-02) condition never evaluate true. i'd mix as:

if keyword in row[0]:     csv_output.writerow([os.path.basename(filename)] + row) 

also, using blank except very, bad idea. if you're looking capture specific exception, define in except clause.
