My immediate reaction is "You never want to do that"

If you're doing something along these lines:

#some code
#create lots of variables
#do stuff with those variables
# <want to delete variables here
#more code

Try converting it to this idiom:

def someFunction(someinput)
  #create lots of variables
  #do stuff with those variables
  return output

#some code
output = someFunction(input)
#more code
