Why is my tkinter toplevel huge when I stated size constraints?

I'm aware this is probably a newb question, but I have yet to be able to find an answer. Here's a snippet of my code, that has a root window containing a button to open a Toplevel. The Toplevel pulls a random line from a text file to function as a sort of idea generator.
import random, fileinput
import tkinter as tk
from tkinter import *
root = tk.Tk()
root.title('Daydreamer')
#fname should be the file name of the image in working directory
fname = "bg.gif"
bg_image = tk.PhotoImage(file=fname)
#get width and height of image
w = bg_image.width()
h = bg_image.height()
#size window correctly
root.geometry("500x400")
cv = tk.Canvas(width=w, height=h)
cv.pack(side='top', fill='both', expand='yes')
cv.create_image(0,0,image=bg_image,anchor='nw')
#add a frame for text
mainframe=tk.Frame(root)
#new window for inspirations
def inspirations():
top = Toplevel(root)
top.geometry=("100x100")
top.title("Inspiration")
def idea():
textidea=None
for line in fileinput.input('textlist.txt'):
if random.randrange(fileinput.lineno())==0:
textidea=line
entrytext=tk.Text(top)
entrytext.insert(INSERT, textidea)
entrytext.insert(END, "Or press the Inspire Me button again for another idea!")
entrytext.pack()
idea()
top.mainloop()
#add buttons
btn1 = tk.Button(cv, text="Inspire Me", command=inspirations)
btn1.pack(side='left', padx=10, pady=5, anchor='sw')
root.mainloop()
Problem is, that Toplevel always comes out absolutely huge (larger than my root window), which looks incredibly silly for the small amount of content being displayed in it. Am I missing something really minute and stupid here? Help much appreciated.

The problem is that you aren't calling the geometry method, you're replacing it with a string.
Change this:
top.geometry=("100x100")
to this:
top.geometry("100x100")

Tkinter: I can't highlight text in text widget

So I made a text editor using tkinter and I used tag_config to highlight the syntax.
CODE
#Importing modules
from tkinter import *
#Main Window
Window = Tk()
Window.minsize(400, 550)
##Main Script
#Defs
#Main frame
main = Frame(Window)
#Main text widget
text = Text(main, bd=0, highlightthickness=0, borderwidth=0, bg="#323232", fg="white")
#Configs
text.config(width=55, height=35)
main.config(width=55, height=35)
#Tag config for coloring syntax
text.tag_configure("import", foreground="yellow")
Window.update()
#Packs and places
#main.place(anchor="c", rely=.5, relx=.5)
main.pack(expand=True, fill=BOTH, side="right")
text.pack(expand=True, fill=BOTH)
#Update window
Window.update()
#Window.mainloop()
Window.mainloop()
PROBLEM
The tag_configure is not working in line 23
text.tag_configure("import", foreground="yellow")
QUESTION
Is there a way to fix that? or Is there any way to highlighting text in tkinter?
EDIT
I add
def check_syntax(event):
text.tag_add('import', 1.0, END)
text.bind("<Return>", check_syntax)
on the code but there are 1 problem, when i run the code and type
import tkinter in the text widget for test and press enter the "tkinter" is highlighted too
How to fix that?

I believe the reason is that you need to actually add a tag first using the tag_add function. You should read this other question with a similar problem. I tried out the code myself and it works. (You'll have to press enter after completing a line)
How to use tkinter tag_config? Python 3.7.3

tag_configure only configures a tag, it doesn't apply the tag to a range of text. To use the tag you need to call tag_add and give it a start and end index. That, or add the tag when calling insert.
For example, this shows how to insert some text, and then apply highlighting to a few characters:
text.insert("end", "import foo\nimport bar\n")
text.tag_add("import", "1.0", "1.6")
text.tag_add("import", "2.0", "2.6")

tkinter fill=Y does not work with Button [duplicate]

I am familiarizing myself with Tkinter, and I am attempting to write a very simple program, which displays a button in a window, using the pack geometry manager.
I was experimenting with various configuration options for pack(), such as expand, fill, and side, and I've run into a peculiar problem. I have written the following code:
from Tkinter import *
root = Tk()
widget = Button(root, text='text')
widget.pack(expand=YES, fill=BOTH)
root.mainloop()
The problem is that the button expands to fill the window in the horizontal direction, but not the vertical direction. This is the same result that I get if instead of specifying fill=BOTH I use fill=X. In addition, if I specify instead fill=Y the button does not expand in either direction. Something seems to be going wrong with the fill in the vertical direction, and I cannot figure out what it might be.
I attempted to Google this problem and surprisingly found no mention of this happening to anyone else. I am using a Mac with OS X Yosemite and running python 2.7.5. I also attempted to compile with python 3.4.1 and saw no change.
Edit:
Based off of the answer and comments below, it is clear that there is nothing wrong with my code, because it seems to work on other machines. If not an error in the code, does anyone know what could possibly be causing the button to not stretch vertically when I run the above code?

This is a feature of native buttons on OSX. Buttons on OSX will be a fixed height and will not expand vertically. There is nothing you can do, short of using a different widget such as a label.

try running this code to see the behavior of fill and expand
from Tkinter import *
root = Tk()
root.geometry("500x500")
widget = Button(root, text='text1')
widget.pack(fill=X, expand=1)
widget = Button(root, text='text2')
widget.pack(fill=Y, expand=1)
widget = Button(root, text='text3')
widget.pack(fill=BOTH, expand=1)
root.mainloop()
Argument fill does fill in vertical direction as well

I am also beginner, defining geometry for fill was missing in your code as given below:
from Tkinter import *
root = Tk()
root.geometry("600x400")
widget = Button(root, text='text')
widget.pack(expand=YES, fill=BOTH)
root.mainloop()

Python Tkinter: How do I apply a new background image when opening a new tk window?

I used the code below (with different variable names for each section) to create a background image for each tkinter window. Each of these is initiated in a function and both work fine independently.
When loading one function from another however, the second fails to display an image. (I have tried importing all relevant in each function aswell). It works in the case that use tk.destruct(), however if If I want to keep it open, or hide it with . withdraw(), the image fails to display, rendering the second window useless.
background_image=tk.PhotoImage(...)
background_label = tk.Label(parent, image=background_image)
background_label.place(x=0, y=0, relwidth=1, relheight=1)

Ok I've made up a solution for you. Basically all you need is to use tk.Toplevel() for the second tkinter window and make sure that the 'parent' is root2 so the image will appear in the second window.
I have used buttons for the images, you had labels so you may wish to change this, but buttons gave me a way to open a new tk window easily, I have also used .pack(), not .place(), as it was faster for me. May also be helpful for you to know that I used python 3.3 with windows so you might need a capital T for tkinter.
import tkinter as tk
root1 = tk.Tk()
def new_window():
root2 = tk.Toplevel()
# click the last button and all tk windows close
def shutdown():
root1.destroy()
root2.destroy()
background_image2 = tk.PhotoImage(file = '...')
background_button2 = tk.Button(root2, image = background_image2, command = shutdown)
background_button2.pack()
root2.mainloop()
background_image1 = tk.PhotoImage(file = '...')
# have used a button not a label for me to make another tk window
background_button1 = tk.Button(root1, image = background_image1, command = new_window)
background_button1.pack()
root1.mainloop()

Python Tkinter Tix: How to use ScrolledWindow with grid in Tix NoteBook

I'm adding several widgets to a Frame which is located in a tix.NoteBook. When there are too much widgets to fit in the window, I want to use a scrollbar, so I put tix.ScrolledWindow inside that Frame and add my widgets to this ScrolledWindow instead.
The problem is that when using the grid() geometry manager, the scrollbar appears, but it is not working (The drag bar occupies the whole scroll bar).
from Tkinter import *
import Tix
class Window:
def __init__(self, root):
self.labelList = []
self.notebook = Tix.NoteBook(root, ipadx=3, ipady=3)
self.notebook.add('sheet_1', label="Sheet 1", underline=0)
self.notebook.add('sheet_2', label="Sheet 2", underline=0)
self.notebook.add('sheet_3', label="Sheet 3", underline=0)
self.notebook.pack()
#self.notebook.grid(row=0, column=0)
tab1=self.notebook.sheet_1
tab2=self.notebook.sheet_2
tab3=self.notebook.sheet_3
self.myMainContainer = Frame(tab1)
self.myMainContainer.pack()
#self.myMainContainer.grid(row=0, column=0)
scrwin = Tix.ScrolledWindow(self.myMainContainer, scrollbar='y')
scrwin.pack()
#scrwin.grid(row=0, column=0)
self.win = scrwin.window
for i in range (100):
self.labelList.append((Label(self.win)))
self.labelList[-1].config(text= "Bla", relief = SUNKEN)
self.labelList[-1].grid(row=i, column=0, sticky=W+E)
root = Tix.Tk()
myWindow = Window(root)
root.mainloop()
Whenever I change at least one of the geometry managers from pack() to grid(), the problem occurs. (Actually, I'd prefer using grid() for all containers.)
When I don't use the NoteBook widget, the problem does not occur either. The other examples here all seem to rely on pack().
Any ideas?
Many thanks,
Sano

I solved it without using ´tix.scrolledWindow´. Instead, I went for the autoscrollbar suggested by Fred Lundh here.
The main problem was the adaption to the NoteBook widget. First, I tried to put the scrollbar to the root, so that they would surround the whole window. Now, I wanted to change the hook for the scrollbar whenever I changed a tab, but the ´raisecmd´ of the Notebook did not work. Next, I thought of using the configure event on each tab - whenever a new tab is raised, its size changes and configure is called.
Well, after much trying without ever being satisfied I changed my approach and put the scrollbars inside of the tabs. The tabs and all subcontainers must get the ´grid_columnconfigure(0, weight=1)´ and ´grid_rowconfigure(0, weight=1)´ settings, or else they will not grow with the tabs.
