def **init**(self):

self.angle = self.angle1

self.angle = self.angle2

What am I doing wrong?? Ive been manipulating this for an hour now…

NVM, as soon as I asked I figured it out… of course

What was the cause of the problem?

“Oops, try again. **init** in Equilateral should take one argument: self” my code is following, pls help

class Triangle(object):

#initiative process

def **init**(self,angle1,angle2,angle3):

self.angle1 = angle1

self.angle2 = angle2

self.angle3 = angle3

number_of_sides = 3

#define a method

def check_angles(self):

if self.angle1+self.angle2+self.angle3 == 180:

return True

else:

return False

my_triangle = Triangle(90,45,45)

print my_triangle.number_of_sides

print my_triangle.check_angles()

#inheritance

class Equilateral(Triangle):

angle = 60

def **init**(self,angle1,angle2,angle3):

self.angle1=self.angle

self.angle2=self.angle

self.angle3=self.angle

class Equilateral(Triangle):

angle = 60

def **init**(self):

self.angle1 = self.angle

self.angle2 = self.angle

self.angle3 = self.angle

Thank you！！it works, but I can’t understand why **init**(self) instead of (self, args1, args2,args3)

Hi, I tried different ways in ipython all OK but codecadmy is more restrict. Good luck.

I am getting this error, “It looks like **init** is missing from Equilateral AND/OR Triangle.”

is there anything wrong with my code?

class Triangle(object):

number_of_sides =3

def **init**(self,angle1,angle2,angle3):

self.angle1 = angle1

self.angle2 = angle2

self.angle3 = angle3

```
def check_angles(self):
sum = self.angle1+self.angle2+self.angle3
if sum ==180:
return True
else :
return False
```

class Equilateral(Triangle):

angle = 60

def init(self):

self.angle1 = self.angle

self.angle2 = self.angle

self.angle3 = self.angle

my_triangle = Triangle(90,30,60)

print my_triangle.number_of_sides

print my_triangle.check_angles()

my_equi = Equilateral(60,60,60)
