How to remove this error: AttributeError: 'Polygon' object has no property 'colour'

I'm trying to simulate a music stage in Python, and I keep coming across this error when trying to add lights to the stage. This is my code below.

import matplotlib.pyplot as plt
import numpy as np
import math
class Light:
def __init__(self, colour, position, direction, intensity, distribution):
self.colour = colour
self.position = position
self.direction = direction
self.intensity = intensity
self.distribution = distribution
def calculate_cone(self):
spread_angle = math.radians(self.distribution)
half_cone_angle = spread_angle/2
start_angle = self.direction - half_cone_angle
end_angle = self.direction + half_cone_angle
class Stage:
def __init__(self, figsize=(10,10)):
self.fig, (self.ax0, self.ax1)=plt.subplots(2, 1, gridspec_kw={'height_ratios': [1, 10]}, figsize = (10,10))
self.ax0.set_aspect("equal")
self.ax0.fill([0,500,500,0],[0,0,50,50],'k')
self.ax1.set_aspect("equal")
self.ax1.fill([0,500,500,0],[0,0,500,500],'k')
self.title=("STAGEVIEW")
self.lights=[]
self.smoke_machines=[]
def add_circle(self, centre, radius, colour):
circle=plt.Circle(centre, radius)
self.ax0.add_patch(circle)
def add_circle(self, centre, radius, colour): 
circle=plt.Circle(centre, radius) 
self.ax0.add_patch(circle) 
def add_light(self, light): 
self.lights.append(light) 
spread=np.array(light.distribution) 
self.ax1.fill(spread[:,0], spread[:,1], colour=light.colour, alpha=0.5) 
def simulate_lights(self): 
for lights in self.lights: 
light.calculate_cone() 
def show(self): 
plt.suptitle(self.title, fontsize="18") 
stage = Stage() 
stage.add_circle([50,25],20, 'steelblue') 
stage.add_circle([150,25],20, 'lightblue') 
stage.add_circle([250,25],20, 'steelblue')
stage.add_circle([350,25],20, 'lightblue')
stage.add_circle([450,25],20, 'steelblue')
lights = [Light(colour="red",position[250,490],direction=90,intensity=1,distribution=[[230,490],[270,490], [270,500],[230,500]])]
for light in lights: 
stage.add_light(light) 
stage.simulate_lights() 
stage.show()

I tried to add a light to my stage, and thought I'd be able to see it in matplotlib, but keep getting this error:
I have changed the light class to the correct class, but now I get a big error message regarding polygon colours.

AttributeError: 'Polygon' object has no property 'colour'

I am not sure what to do with this error. I am going to be trying to add multiple lights, to match the circles on the 'stage', but I cannot even get one light to work.

I appreciate the help.

I'm just learning Python, so it can be hard to me to see where I went wrong.

Thank you

I figure it out now, it is "color" not "colour".<br>
Also I change some codes, you can check it like: <br>

spread_angle = np.radians(self.distribution)
...
self.ax1.fill(spread[:,0], spread[:,1], color=light.colour, alpha=0.5)
...
plt.show()
plt.close()
# stage.show()

the whole codes is here<br>

import matplotlib.pyplot as plt
import numpy as np
import math
class Light:
def __init__(self, colour, position, direction, intensity, distribution):
self.colour = colour
self.position = position
self.direction = direction
self.intensity = intensity
self.distribution = distribution
def calculate_cone(self):
spread_angle = np.radians(self.distribution) #np.array([math.radians(i) for i in self.distribution])
half_cone_angle = spread_angle / 2
start_angle = self.direction - half_cone_angle
end_angle = self.direction + half_cone_angle
class Stage:
def __init__(self, figsize=(10,10)):
self.fig, (self.ax0, self.ax1)=plt.subplots(2, 1, gridspec_kw={'height_ratios': [1, 10]}, figsize = (10,10))
self.ax0.set_aspect("equal")
self.ax0.fill([0,500,500,0],[0,0,50,50],'k')
self.ax1.set_aspect("equal")
self.ax1.fill([0,500,500,0],[0,0,500,500],'k')
self.title=("STAGEVIEW")
self.lights=[]
self.smoke_machines=[]
def add_circle(self, centre, radius, colour):
circle=plt.Circle(centre, radius)
self.ax0.add_patch(circle)
def add_light(self, light): 
self.lights.append(light) 
spread=np.array(light.distribution) 
self.ax1.fill(spread[:,0], spread[:,1], color=light.colour, alpha=0.5) 
def simulate_lights(self): 
for lights in self.lights: 
lights.calculate_cone() 
def show(self): 
plt.suptitle(self.title, fontsize="18") 
stage = Stage() 
stage.add_circle([50,25],20, 'steelblue') 
stage.add_circle([150,25],20, 'lightblue') 
stage.add_circle([250,25],20, 'steelblue')
stage.add_circle([350,25],20, 'lightblue')
stage.add_circle([450,25],20, 'steelblue')
lights = [Light(colour="red",position=[250,390],direction=90,intensity=1,distribution=[[230,390],[270,390], [270,500],[230,500]])]
for light in lights: 
stage.add_light(light) 
stage.simulate_lights() 
plt.show()
plt.close()
# stage.show()

this is result:<br>

You are trying to pass the colour attribute of the Light class.

But instead of using light.colour, you're using self.colour, which references the class Stage, which does not have the colour attribute, thus raising this error.

Updating your add_light method from this:

def add_light(self, light):
    self.lights.append(light)
    spread=np.array(light.distribution)
    self.ax1.fill(spread[:,0], spread[:,1], colour=self.colour, alpha=0.5)

to this:

def add_light(self, light):
    self.lights.append(light)
    spread=np.array(light.distribution)
    self.ax1.fill(spread[:,0], spread[:,1], colour=light.colour, alpha=0.5)

would solve your issue.
