How does Python know that the next line is the continuation of your if 
statement, instead of the beginning of a new line of code?  You didn't 
do anything to indicate continuation, so it takes this as an incomplete 
statement. "If ... stuff ... or... (or what??)"

You need to END that line with a backslash

if (abs(...height()/2) or \

or else make the line break INSIDE a set of parentheses, for Python to 
keep looking to the next line(s) to complete the statement.
