1. Identify the error.
class Triangle:
def __init__(base, altitude):
self._base = base
self._altitude = altitude
In Exercises 2 through 10, assume that the code shown below is contained in the file circle.py and
determine the output produced by the lines of code.
class Circle:
def __init__(self, radius=1):
self._radius = radius
def setRadius(self, radius):
self._radius = radius
def getRadius(self):
return self._radius
def area(self):
return 3.14 * self._radius * self._radius
def circumference(self):
return 2 * 3.14 * self._radius
