Thread: Python Help

i'm new using classes in python, python in general, , i'm not sure i'm doing wrong this. i'm hoping can tell me how fix this.

code:

class cp:  	x = x/1000  	def o2(self, x):  		self.state = 30.03235 + 8.772972*x + (-3.988133*x**2) + (0.788313*x**3) - 0.741599/(x**2)  	def n2(self, x):  		self.state = 19.50583 + 19.88705*x + (-8.598535*x**2) + (1.369784*x**3) + 0.527601/(x**2)  print(cp.o2(1500))

code:

class cp:     x = x/1000     def o2(self, x):         self.state = 30.03235 + 8.772972*x + (-3.988133*x**2) + (0.788313*x**3) - 0.741599/(x**2)     def n2(self, x):         self.state = 19.50583 + 19.88705*x + (-8.598535*x**2) + (1.369784*x**3) + 0.527601/(x**2) print(cp.o2(1500))

you calling method on class , not instance of class. try

code:

c = cp() print(c.o2(1500))

edit: didn't enough, there more problems: functions o2 , n2 should return value if want print something.
