#Dont know if this has been done
#a lot before, but I
#got inspired from the web site
#http://p-nand-q.com/python/stupid_lambda_tricks.html
#and tried to write a lambda that
#is a complete program, except for
#the import.
#Sure a lot of fun to write.

import sys #For the write function
#All variables are inside of the lambda

#start main lambda body
