Answer 1

the .bat code for this
for %f in (*.txt) do type "%f">> output.txt
it takes all the .txt files in selected folder merge them and save the output as output.txt you will have to name .py .txt
the bat doesnot delete other .py

I understood that you want a code that merges the extra words of a text file with the other without doing it
so this is code in windows batch script that merges two text files

Answer 2

If you want to append some text in python, you should use 'a' option of open() function. This code appends 'Appended text' to the end of every *.txt file in mydir directory:

from os import listdir, path
mydir = r'C:\text'
for filename in filter(lambda x: x.endswith('.txt'), listdir(mydir)):
with open(path.join(mydir, filename), 'a') as f:
f.write('Appended text')
