My friend told me print in language doesn't mean print as in paper and ink.
Context matters (and you got it wrong) :) Your question is actually a tad vague.
Are you asking if you want dump the contents of all the file in a folder to standard output? That is, dump the output of one file to standard output, wait for confirmation, dump the second one, and so on?
I was thinking, "too bad you're not on a *NIX, you could just write a small shell script to repeatedly cat all the files in a directory". You can actually get cat for Windows, as there is a windows port.
In any case, what you probably want to do is use Python to get a list of all the files in a directory. Look at
Python docs and more Googling for examples.
You can then for each file repeatedly extract it line by line and then dump the line to output. Or call cat on said file.
