This function:

 def fromString(self, str):
  #creates a Craft object from the string
#end class Craft


Is completely empty (the comment lines are discarded). So Python expects any next piece of code to be inside this method (and thus indented).
If you want an empty function, use 'pass' instead.

(also consider using four spaces for indentation, which I've also found much clearer. Have a read through PEP 8; has a lot of interesting tidbits. 
And an editor with a good Python mode is very handy, because that would have almost automatically indented the next piece of code, 'class Battleship(Craft)', which would have indicated something went awry before that line).
