在子目录的文件中串联多个.txt

Question

I have multiple .txt files in different levels of subdirectory. All txt files are in the final iteration, that is, there is no level with both .txt files and further directories. I want to concatenate them all into one new text file, but can't find a simple way to go through all the subdirectories.

A command I've found, that is to be entered into the python command line terminal thus:

$ cat source/file/*.txt > source/output/output.txt

But I am not sure how I could make this iterate over multiple subdirectories. (I am a real beginner with python, there seems to be some confusion. Is this not a python command? The source I found it from claimed it was...)

You could build them using a python script using something like:

file_list = ['c:\data.txt', 'c:\folder1\data.txt']

for everything in file_list:
    f = open(everything)
    for line in f.readlines():
        print line

Call the script from cmd eg \\python.exe 'buildtxtfiles.py'
