one line to fix

Question

lat1 = float(radians(self.lat))

while debugging, it states "must be real number, not a string." How do I fix this?

Answer 1

float() is able to convert to string to a float. The problem here is caused because the program evaluates in to out. It first tries radians(self.lat) and fails so it raises that error. The fix would be to first convert the string self.lat to a float before putting it into the radians function. So switch the order of evaluation.

radians(float(self.lat))
