I get invalid syntax error for line 14 and 37 but cannot find any indent or character errors.

Any ideas.

Thx

There are a few things.

Look at how estimated_cost= is defined. You left out key pieces of information in the formula. Remember, you’re using class variables here so you have to use the self keyword.

estimated_cost = 250 * self.age - 128 * self.sex …etc

Also, revisit how you utilized the .format() function.
Your code: print("{0}'s estimated insurance costs are {1}".format(self.name, str(estimated_cost))

Summary

You don’t really need to use “{0}” and “{1}” b/c Python replaces the placeholders by value in order that they’re listed. You also don’t need to convert the second items to str().

@linguisticsconsultin,

As already mentioned, make sure you include the self keyword for all the attributes.

There actually isn’t a problem with your formatted strings, though. You’re just missing a whole bunch of closing parentheses.
