The division operation in your generator expression raises an exception in this case. Eager evaluation would raise this error at the point you create the object. You can replace the parentheses with square brackets to create a list comprehension instead of a generator: Python >>> average_points...
Properties are enclosed by curly brackets ({}), the key is followed by a colon, and the value is enclosed by single or double quotation marks. In case you have already added Sally and John as node labels, but want to change them into node properties, you need to refactor your graph. ...
