Putting frames on separate lines

[kenwatts275]

Hello. I am trying to create an input window that prompts for two files.
I created two frames, frame1 and frame2. I inserted a label and entry widget in each frame.
When I run the program, it puts everything on a single line.
I would like to put the prompts on separate lines.
Below is an excerpt of the code I wrote.
Thanks in advance!

mw = Tk()
# 999x999 is size of window, 999+999 is the location of the window
mw.geometry('800x400+400+200')
mw.title("Test Program")

frame1 = Frame(mw).pack(side=TOP,anchor=W,fill=X,expand=YES)
frame2 = Frame(mw).pack(side=TOP,anchor=W,fill=X,expand=YES)
framebot = Frame(mw).pack(side=BOTTOM,anchor=W,fill=X,expand=YES)



w1 = Label(frame1, text="Input File: ",font=("Times",25)).pack(side=LEFT)
e1 = Entry(frame1,width=25,font=("Times",25))
e1.insert(0, "infile.txt")
e1.pack(side=LEFT)

Button(frame1,text='Search',font=("Times",25),command=get_file1).pack(side=LEFT)


w2 = Label(frame2, text="Output File: ",font=("Times",25)).pack(side=LEFT)
e2 = Entry(frame2,width=25,font=("Times",25))
e2.insert(0, "outfile.txt")
e2.pack(side=LEFT)

Button(frame2,text='Search',font=("Times",25),command=get_file2).pack(side=LEFT)


Button(framebot,text='Go',font=("Times",25),command=show_entry_fields).pack()
Button(framebot,text='Exit',font=("Times",25),command=mw.quit).pack()

mw.mainloop()

I want each prompt to be on its own line as show in the following image:

But the above program produces all the prompts on a single line:

Below is my full python program in case you cannot figure it out from the program excerpt.
When you run the program, all the frames appear on the same line.
If anybody can figure out why it does this, it would be appreciated.

from tkinter import filedialog
from tkinter import *
import tkinter.font as font
#import tkinter as tk

def show_entry_fields():
	fname1 = e1.get()
	fname2 = e2.get()
	print("Input File: %s\nOutput File: %s" % (fname1, fname2))

	f1 = open(fname1,"r")
	lines = f1.readlines()
	for x in lines:
		print(x)
	f1.close()



def get_file1():
	file1 =  filedialog.askopenfilename(title = "Select file",filetypes = (("all files","*.*"),("jpeg files","*.jpg"),("python files","*.py")))
	e1.delete(0,'end')
	e1.insert(0,file1)

def get_file2():
	file2 =  filedialog.askopenfilename(title = "Select file",filetypes = (("all files","*.*"),("jpeg files","*.jpg"),("python files","*.py")))
	e2.delete(0,'end')
	e2.insert(0,file2)



mw = Tk()
# 999x999 is size of window, 999+999 is the location of the window
mw.geometry('800x400+400+200')
mw.title("Test Program")

frame1 = Frame(mw).pack(side=TOP,anchor=W,fill=X,expand=YES)
frame2 = Frame(mw).pack(side=TOP,anchor=W,fill=X,expand=YES)
framebot = Frame(mw).pack(side=BOTTOM,anchor=W,fill=X,expand=YES)



w1 = Label(frame1, text="Input File: ",font=("Times",25)).pack(side=LEFT)
e1 = Entry(frame1,width=25,font=("Times",25))
e1.insert(0, "infile.txt")
e1.pack(side=LEFT)

Button(frame1,text='Search',font=("Times",25),command=get_file1).pack(side=LEFT)


w2 = Label(frame2, text="Output File: ",font=("Times",25)).pack(side=LEFT)
e2 = Entry(frame2,width=25,font=("Times",25))
e2.insert(0, "outfile.txt")
e2.pack(side=LEFT)

Button(frame2,text='Search',font=("Times",25),command=get_file2).pack(side=LEFT)


Button(framebot,text='Go',font=("Times",25),command=show_entry_fields).pack()
Button(framebot,text='Exit',font=("Times",25),command=mw.quit).pack()

mw.mainloop()

I found the problem with the program.
The problem is caused by defining the frames and packing them at the same time.
The following code is incorrect:

frame1 = Frame(mw).pack(side=TOP,anchor=W,fill=X,expand=YES)
frame2 = Frame(mw).pack(side=TOP,anchor=W,fill=X,expand=YES)
framebot = Frame(mw).pack(side=BOTTOM,anchor=W,fill=X,expand=YES)

The correct code is as follows:

frame1 = Frame(mw)
frame2 = Frame(mw)
framebot = Frame(mw)
frame1.pack(side=TOP,fill=X)
frame2.pack(side=TOP,fill=X)
framebot.pack(side=BOTTOM,fill=X)
