How can I concatenate external files (all the little *.htm files in a directory) into one big file?

import sys, string, glob, os

#First I create a list:
fls = glob.glob('C:\\wxpython\\wxPython-2.1.16\\docs\\wx\\wx*.htm')

#Then I guess I should open an output file for writing
outfile = open('temp.txt,'w')

for x in fls:
               file=open(x,'r')
               data=file.read()
               file.close()
               outfile.write(data)

outfile.close()

We then iterate over fls to give us each file name and open each one.
We then call the read method against it, which loads in the entire file
and assign that to data. we close the file and write the data to our
outfile. And then on to the next file. Finally we close the outfile.

You have to use read() with some caution because it (trys) to load the
whole file into memory which maybe an issue if it was sizable. In your
case it isn't an issue because they are simple html files.
