combine multiple text files into one text file using python [duplicate]

Answer 1

You can read the content of each file directly into the write method of the output file handle like this:

import glob

read_files = glob.glob("*.txt")

with open("result.txt", "wb") as outfile:
    for f in read_files:
        with open(f, "rb") as infile:
            outfile.write(infile.read())

Answer 2

The fileinput module is designed perfectly for this use case.

import fileinput
import glob

file_list = glob.glob("*.txt")

with open('result.txt', 'w') as file:
    input_lines = fileinput.input(file_list)
    file.writelines(input_lines)

Answer 3

filenames = ['resultsone.txt', 'resultstwo.txt']
with open('resultsthree', 'w') as outfile:
    for fname in filenames:
        with open(fname) as infile:
            for line in infile:
                outfile.write(line)

Answer 4

You could try something like this:

import glob
files = glob.glob( '*.txt' )

with open( 'result.txt', 'w' ) as result:
    for file_ in files:
        for line in open( file_, 'r' ):
            result.write( line )

Should be straight forward to read.

Answer 5

It is also possible to combine files by incorporating OS commands. Example:

import os
import subprocess
subprocess.call("cat *.csv > /path/outputs.csv")
