Pause function in pygame mixer is not working

I am currently making a GUI with Tkinter that plays music. The program is able to correctly play the songs, and I am trying to implement a pause button. This is the code I have, does anyone know why this might not be working? I know the button is linked properly since I have tried printing something out when the button is clicked, and that works. Also, there are no error messages, the audio is just not pausing.

How can i 'get' the number i have entered into the label widget into a variable?

I I have 2 functions and the second function should run after the button in the first one has been clicked. This works fine, however I need the number that has been entered to go into a variable and so far the .get() function is not working and im not sure what to do.
I have looked at a lot of different examples, including login and sign up gui's however none of them have been able to help.
from tkinter import *
import tkinter.messagebox as box
def enter_rle_1():
enter_rle = Tk() #do not remove
enter_rle.title('Enter RLE') #do not remove
frame = Frame(enter_rle) #do not remove
label_linecount = Label(enter_rle,text = 'Linecount:')
label_linecount.pack(padx=15,pady= 5)
linecount = Entry(enter_rle,bd =5)
linecount.pack(padx=15, pady=5)
ok_button = Button(enter_rle, text="Next", command = linecount_button_clicked)
ok_button.pack(side = RIGHT , padx =5)
frame.pack(padx=100,pady = 19)
enter_rle.mainloop()
def linecount_button_clicked():
Linecount = linecount.get()
if int(Linecount) < 3:
tm.showinfo("Error", "Enter a number over 3")
elif int(Linecount) > 1000000000:
tm.showinfo("Error", "Enter a number under 1,000,000,000")
else:
print("fdsfd")
enter_rle_1()
I expect there to be a popup telling me the number is too big or too small, depending on wether the number is or not, and if it is a good number, i just have it set as a print as some code to test to see if it works before i move on.

Define a String variable for the Entry widget (Make sure it is global defined):
global linecount_STR
linecount_STR = StringVar()
linecount_STR.set('Enter value here')
linecount = Entry(enter_rle,bd =5,textvariable=linecount_STR)
linecount.pack(padx=15, pady=5)
The number entered there can then be read with int(linecount_STR.get()).

i suggest an OO approach, look this code

Python - pass value back to main() based on when a button is pressed

Forgive me if this is a badly mangled way of doing things, but I'm new to development in general.
I am trying to create a window with a number of buttons using tkinter, each button having the name of a player on it using a class called from main().
I then want to be able to use the name on the button that is pressed later in the app, so I want to pass that back to main(). So, if I click on the Annie button, I want to open up a new window later called 'Options for Annie' and I'm assuming that the value 'Annie' needs to be passed back to the main function.
My main code:
<imports appear here>
def main():
players = ['Annie','Benny','Carrie','Donny']
winHome = playerWindow(root,players)
print("In main() : " + winHome.selected)
root.mainloop()
if __name__ == "__main__":
main()
My class code:
<imports appear here>
root=Tk()
class playerWindow():
def selectPlayer(self,selname):
self.selected = selname
print("In class: " + self.selected)
def __init__(self, master, players=[]):
colours = ['red','green','orange','white','yellow','blue']
self.selected = ""
r = 0
for p in players:
randcol = random.randint(0,len(colours))-1
if colours[randcol] in ('blue','green'):
fgcol='white'
else:
fgcol='black'
playername = delplayer = p
playername = Button(root, text=playername, bg=colours[randcol], fg=fgcol, width=15, command=lambda name = playername:self.selectPlayer(name)).grid(row=r,column=0)
s = ttk.Separator(root, orient=VERTICAL)
delplayer = Button(root, text='Del', bg='grey', fg='red', width=5, command=lambda name = delplayer: print("Delete Player %s" % name)).grid(row=r,column=1)
r = r + 1
Button(root, text="New Player", fg="black", command=lambda: print("New Player Functionality"), width=15).grid(row = len(players)+3,column=0)
Button(root, text="QUIT", fg="red", command=root.destroy, width=15).grid(row = len(players)+3,column=1)
What is happening is that the window gets created, the next line in main() is run (my added print statement) which is empty, obviously as main is continuing. When I press the button, the sleectPlayer function is called and works.
Somehow I need to get the value back to main() to go on to the next task using that value, however I don't seem to be able to frame the question correctly to get the answers I need.
Any help would be greatly appreciated.
I am using Python 3.5.1

You are already accessing it. I personally don't like returning to the main function, instead I suggest creating a top-level class to link back to. This should help make things flow better.

randcol = random.randint(0,len(colours))-1

fgcol='white'
else:
fgcol='black'
playername = delplayer = p
playername = tk.Button(master, text=playername, bg=colours[randcol], \

You never pack the button frame.
