Hi Neo...

Even the best written code can be hard to understand after we have not touched it for a month or two, let alone a year or more.

Yup, I often do a search for something and come across an upload I have written and totally forgotten about. I read it and think did I actaully write that?

So, I learned the hard way many years ago not to write "fancy one liners" and write well documented code and scripts.

Going slightly off topic here with the second quote I was on a Python ML, (they were so obnoxious that I have long since left), and the big guns on there said there was no need to add comments as it was easy to work out what a python script does. I gave them this challenge:-
(Before reading the answer I wonder if the Python experts on here can work out what it does?)

Code:

# SomeSound.py

audio=file('/dev/dsp', 'wb')
def main():
	for a in range(0,25,1):
		for b in range(15,112,1):
			for c in range(0,1,1):
				audio.write(chr(127+b)+chr(127+b)+chr(127+b)+chr(127+b)+chr(127-b)+chr(127-b)+chr(127-b)+chr(127-b))
		for b in range(112,15,-1):
			for c in range(0,1,1):
				audio.write(chr(127+b)+chr(127+b)+chr(127+b)+chr(127+b)+chr(127-b)+chr(127-b)+chr(127-b)+chr(127-b))
main()
audio.close()

       Options feature the following.

	      -port num : specify the port number.
	      -st : print miscellaneous status data.
	      -sx : input data is evaluated as a hexadecimal data string.
	      -sep chr : specify the separator of the input data.
	      -dk : use the function `tcrdbputkeep' instead of `tcrdbput'.
	      -dc : use the function `tcrdbputcat' instead of `tcrdbput'.
	      -dai : use the function `tcrdbaddint' instead of `tcrdbput'.
	      -dad : use the function `tcrdbadddouble' instead of `tcrdbput'.

	      -m num : specify the maximum number of the output.
	      -pv : print values of records also.
	      -fm str : specify the prefix of keys.

       If the port number is not more than 0, UNIX domain socket is used and the path of the socket file is specified by the host parameter.  This
       command returns 0 on success, another on failure.
