AttributeError when trying to change tkinter label color with bound command

I am trying to create a tkinter label that changes color when clicked to show that it has been visited. I keep getting an attribute error saying that Show_Label has no attribute 'fg'. Please help! Here is the code being used.
class Sheet_Label(Label):
def __init__(self,master,text):
Label.__init__(self,master,text=text,cursor="hand2",font="Times 16 underline",fg="blue")
def button_click(event):
if self.fg =="blue":
self.fg = "purple"
else:
self.fg = "purple"
location = os.getcwd()
file = webbrowser.open_new(location + '\\' + "hello.txt")
self.bind("<Button-1>",func=button_click)
def sheets_view():
sheets_window = Toplevel(window)
hello = modules.Sheet_Label(master=sheets_window,text="Hello")
hello.pack(padx=10,pady=10)
sheets_window.title("Production Sheets")
sheets_window.focus()
x = (screen_width/2) - (500/2)
y = (screen_height/2) - (500/2)
sheets_window.geometry("%dx%d+%d+%d" % (500,500,x,y))
sheets_window.resizable(0,0)
Here is the error message:

You aren't initializing self.fg until button_click has been called, but at that point it's too late because you're trying to reference self.fg before setting it.
Also, self.fg is not the same as the fg attribute when you create the widget (eg: Label(..., fg="blue"). If you want to get the value of the widget attribute you should use self.cget('fg') or use the shortcut self['fg']. If you want to set it from within the class itself you should use self.configure(fg="purple").

TypeError: 'float' object is not callable error while calling a function

This is the code I currently have:
def uniform_distribution(users,radius):
user_coordinates_distance=[]
user_coordinates=[]
finding_shadowing=[]
r=radius*np.sqrt(np.random.uniform(0,1,users))
angle=2*np.pi*np.random.uniform(0,1,users)
x = r*np.cos(angle)
y = r*np.sin(angle)
user_distance = np.sqrt(x*x+y*y)
x_shadowing=1000*x
y_shadowing=1000*y
x_shadowing=(x_shadowing-x_shadowing%10)/10
y_shadowing=(y_shadowing-y_shadowing%10)/10
finding_shadowing=shadowing(x_shadowing,y_shadowing,shadowing_matrix)
print(finding_shadowing)
for i in range (0,users):
user_coordinates=[x[i],y[i],user_distance[i],finding_shadowing[i]]
user_coordinates_distance.append(user_coordinates)
return (user_coordinates_distance)
And this is the error I get when I run it:
Traceback (most recent call last):
File "C:\Users\Ajit\Desktop\maryland\Sem 2\ENTS 656\project656\main program and functions\main_1.py", line 136, in <module>

What exactly does this error mean?

Deep-learning library Neon DataIterator / ArrayIterator init error

When trying to set up the DataIterator as explained on neon tutorial.
from neon.data import DataIterator
import numpy as np
X = np.random.rand(10000, 3072)
y = np.random.randint(1, 11, 10000)
train = DataIterator(X=X, y=y, nclass=10, lshape=(3, 32, 32))
I encountered a weird error:
ERROR:neon.data.dataiterator:DataIterator class has been deprecated and renamed"ArrayIterator" please use that name.
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "neon/data/dataiterator.py", line 168, in __init__
super(DataIterator, self).__init__(*args, **kwargs)
File "neon/data/dataiterator.py", line 82, in __init__
self.Xdev = [self.be.array(x) for x in X]
AttributeError: 'NoneType' object has no attribute 'array'
I then tried with ArrayIterator, keeping X, y the same.
ArrayIterator(X=X, y=y, nclass=10, lshape=(3,32,32))
With the same NoneType error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "neon/data/dataiterator.py", line 82, in __init__
self.Xdev = [self.be.array(x) for x in X]
AttributeError: 'NoneType' object has no attribute 'array'
Why would this be the case? Is there an easy fix?

Fixed the problem by generating backend.
from neon.backends import gen_backend
be = gen_backend()
(...)

TypeError: 'module' object not callable

I have searched thoroughly before posting this. I seem to have a 'module' object not callable error. Here is my code:
""" Create Snake """
def createSnake():
x = randrange(0, 720, 20)
y = randrange(0, 480, 20)
size = 3
snakeBox = ""
snake = []
for i in range(size):
snakeBox = pygame.rect((x + 20*size, y + 20*size), (20, 20))
snake.append(snakeBox)
return snake
This is the error I recieve on execution:
root#raspberrypi:/home/pi/Codes/Snake# python Snake.py

File "Snake.py", line 49, in createSnake
snakeBox = pygame.rect((x + 20*size, y + 20*size), (20, 20))
TypeError: 'module' object is not callable
I cannot seem to figure out what the error is as I think I have imported my modules correctly
from pygame.locals import *
Thank you for your help :')

It seems likes a simple typo of pygame.Rect.
Replace:
pygame.rect
with:
pygame.Rect

Debugging sample pygame code. Possibly error with super(), yet again

Can't figure out what's wrong. All I know is that it doesn't execute. Find the trackback at the bottom.
EDIT: UPDATED, still doesn't run as should...

It's the images = PhelpsAnimation.thePhelpsfiles parameter. thePhelpsfiles is not an attribute of the PhelpsAnimation class you've defined. It should work if you change that to just images=thePhelpsfiles.
