So I was having problems with a code before because I was getting an empty line when I iterated through the foodList.

Someone suggested using the 'if x.strip():' method as seen below. 

for x in split:
  if x.strip():
    foodList = foodList + [x.split(",")]

It works fine but I would just like to know what it actually means. I know it deletes whitespace, but wouldn't the above if statement be saying if x had empty space then true. Which would be the opposite of what I wanted? Just would like to wrap my ahead around the terminology and what it is doing behind the scenes.

python if-statement strip
