Chess game using Tkinter GUI, Moving the pieces

I am currently working on a chess game as the A-Level programming project and I am having trouble getting the pieces to move across the board. The canvas.move() function that i am using doesn't seem to move the images and i have tried other functions including canvas.coords() any help would be appreciated.
This is the code for moving the pieces:
piece = None
def getorigin(eventorigin):
global Posx,Posy, piece
Posx = eventorigin.x
Posy = eventorigin.y
Xcase = math.ceil((Posx / 62)) - 1
Ycase = math.ceil((Posy / 62)) - 1
if Matrix[Ycase][Xcase] != "":
# select the piece
piece = Matrix[Ycase][Xcase]
preY = Ycase
preX = Xcase
print(piece)
elif piece:
# a piece is selected, so move the piece
canvas.move(piece, Xcase*62.5+33, Ycase*62.5+33)
Matrix[Ycase][Xcase] = piece
Matrix[preY][preX] = ""
piece = None # deselect the piece
piecePosition()
canvas.bind("<Button-1>", getorigin)
root.title("Chess")
root.iconbitmap()
root.geometry("500x500")
root.mainloop()
This is the matrix grid being used as the board:
Matrix= [["bRook","bKnight","bBishop","bQueen","bKing","bBishop","bKnight","bRook"],
["bPawn","bPawn","bPawn","bPawn","bPawn","bPawn","bPawn","bPawn"],
["","","","","","","",""],
["","","","","","","",""],
["","","","","","","",""],
["","","","","","","",""],
["wPawn","wPawn","wPawn","wPawn","wPawn","wPawn","wPawn","wPawn"],
["wRook","wKnight","wBishop","wQueen","wKing","wBishop","wKnight","wRook"]]

Why does my program require me to press the enter key before continuing (python tkinter)

I am making a program, using python tkinter, which simply prints some circles to the screen (I call it a board in this program). The program moves on to a different "board" once the mouse cursor moves over the button. The problem I have is that I simply call the "create_board" function 3 times using a for loop however in-between each iteration of the loop the "enter" key must be pressed. This isn't a massive deal but I'm trying to understand why and if there is a way to remove this requirement and have the next board load automatically.
I'm certain it has something to do with the tkinter windows and triggering the command "destroy" once the buttons (circles) are pressed however I'm still learning how to effectively use tkinter and any help would be very much appreciated.
def create_board(user_name, board):
# define the name of tkinter window
win = Tk()
# get the size of the displace for position and size calculations
app = wx.App(False)
w, h = wx.GetDisplaySize()
name = user_name
# define variables based on board number
if board == 0:
gx_pos = int(w/8) # locations of circles
gy_pos = int(h/8)
bx_pos = (w/8)*5
by_pos = (h/8)*5
board_num = str(1)
elif board == 1:
gx_pos = int(w/12)
gy_pos = int(h/12)
bx_pos = (w/6)*5
by_pos = (h/6)*5
board_num = str(2)
elif board == 2:
gx_pos = int(w/3)
gy_pos = int(h/3)
bx_pos = (w/3)*2
by_pos = (h/3)*2
board_num = str(3)
# records the mouse cursor position into a file along with time taken
def record_pos(x, y, board_num, s):
filename = name + "_" + board_num + ".txt"
try:
os.path.isfile('./'+filename)
except:
open(filename, 'r')
with open(filename, 'a') as f:
f.write(str(x) + "," + str(y) + "," + str(s) + "\n")
# determining when left click should be made
def mouse_pos():
flags, hcursor, (x, y) = win32gui.GetCursorInfo()
time_taken = time.time()
record_pos(x, y, board_num, time_taken)
mouse.click('left')
win.after(500, mouse_pos)
# wait 3 seconds before loading first board
time.sleep(3)
geometry = "%dx%d" % (w,h)
win.geometry(geometry)
win.attributes('-fullscreen', True)
win.config(cursor="circle")
# get the grid image
bg = Image.open("grid_image.png")
img = bg.resize((w, h))
grid_img=ImageTk.PhotoImage(img)
image_label = Label(win, image=grid_img)
image_label.place(x=0, y=0, relwidth=1, relheight=1)
# print an image of a green circle
gw = int(w/26)
gh = int(h/15)
g_circle = Image.open('green_circle.png')
g_img = g_circle.resize((gw,gh))
g_circle_image=ImageTk.PhotoImage(g_img)
g_label = Label(win, image=g_circle_image)
g_label.place(x = gx_pos,y = gy_pos)
g_btn = Button(win, image=g_circle_image, command = win.destroy)
g_btn.place(x= gx_pos , y= gy_pos)
# print an image of a blue circle
bw = int(w/26)
bh = int(h/15)
b_circle = Image.open('circle.png')
b_img = b_circle.resize((bw,bh))
b_circle_image=ImageTk.PhotoImage(b_img)
b_label = Label(win, image=b_circle_image)
b_label.place(x=bx_pos, y=by_pos)
b_btn = Button(win, image=b_circle_image, command = win.destroy)
b_btn.place(x=bx_pos, y=by_pos)
# record mouse position
mouse_pos()
win.mainloop()
EDIT: I added the simple for loop that I'm using to iterate through the boards.
for i in range(3):
create_board(user_name, i)

The issue was caused by using time.sleep() in tkinter. After removing this the code runs with out requiring an enter key press each time.

How can I get my game of life code to animate in python?

I'm currently writing the John Conway's game of life in python and I'm stuck when it comes getting the cells to animate according to the rules. currently my code is compiling without any errors but I just can't figure out how I can get the code to animate. My code is:

I am new to python so please forgive me if you see any errors I've missed and thank you for any help you are able to give me.

I think you need a few modifications:
Change your Button to start the drawing: start_button = Button(window, text='Start Game', command=apply_rules)
Modify def apply_rules(): to have this addition at the end: window.after(0, apply_rules)
Don't call apply_rules() your self: apply_rules()
When you run the program you will need to press the Start Game button.
================
Update:
You may need to add another function to encapsulate the idea of running the rules and displaying the results continuously:
Keep def apply_rules(): as you have it in your posting and add a new function:
def one_cycle():
apply_rules()
draw_grid()
window.after(1, one_cycle) # use 1 to ease performance as Bryan suggests
Change the Button command to: command=one_cycle
Now you only need this at the bottom:
create_grid()
window.mainloop()

tkinter cant assign text variable

the problem was my input popup had to be a toplevel window so changing tk.Tk() to tk.Toplevel() makes it work fine ;)

I don't understand exactly what your problem is doing wrong, but I'm pretty sure I know what the problem is.
Most of your program is using some library named graphics to run a GUI. Then you're trying to use Tkinter to run another GUI in the same program.
I don't know what that graphics library that is, but unless it's either built on top of Tkinter, or specifically designed to work with Tkinter, this is unlikely to work. Both of them are going to try to be in charge of the one and only GUI for your program, handling all of the events from the user/windowing system, and so forth. One or both are going to fail.
In fact, even if graphics were built on top of Tkinter or designed to work together with it, calling mainloop on the Tkinter window is at best going to freeze up the rest of your GUI until you exit that mainloop, and at worst going to break the outer mainloop that the other GUI is relying on.
From what I can see from your other code, that graphics library seems to have enough features to do everything you were trying to do with Tkinter—create a new window, place some widgets on it, handle a button click. So, why not just use that?
Now that you've given us a link to the graphics library you're using… it looks like a thin wrapper around Tkinter. Which means you should be able to integrate them easily. You just have to create a new Toplevel instead of a root window (since graphics has already created a Tkinter root), and not call mainloop or quit (because you're already in a Tkinter main loop created by graphics).
Since you haven't given us an SSCCE that I can just run and hack on, I've built my own super-simple one around the first example in the graphics docs, which does what you were trying to do, and also shows how you can interact with the graphics window from the Tkinter code.
from graphics import *
import Tkinter as tk
def getString(ment,mGui):
global win
print(ment.get())
mGui.destroy()
win.close()
def inputWin():
global hsname
mGui = tk.Toplevel()
ment = tk.StringVar()
mGui.title('New Highscore!')
tk.Entry(mGui,textvariable=ment).pack(side=tk.LEFT)
tk.Button(mGui,text='OK',command=lambda:getString(ment,mGui),fg='red',bg='blue').pack(side=tk.RIGHT)
win.getMouse()
def main():
global win
win = GraphWin("My Circle", 100, 100)
c = Circle(Point(50,50), 10)
c.draw(win)
win.getMouse() # Pause to view result
inputWin()
main()
It would be better to refactor this to eliminate your global variables, either using an OO design (create a class so you can store things as instance attributes) or a functional design (pass values through closures or bake them in with lambda/partial, as you're already doing in your Button command), but I tried to follow the style you already set in your code rather than rewrite everything.

Making Tkinter Photoimage crashes python program

I'm writing a minesweeper game using tkinter, and everything appears to function alright, but python crashes every time after a number of clicks, and I believe it is because I've added images for the "flags" used to flag where a mine is. Below is the function that draws all of the cells, which is called with each move/click.
def draw_cake_cell(canvas, row, col):
# draws different cells on the board (blank cell, numbers, cake flags)
margin = 5
cellSize = 30
board = canvas.data['board']
mask = canvas.data['mask']
cake_count = canvas.data['cake_count']
player_board = canvas.data['player_board']
left = margin + col*cellSize
top = margin + row*cellSize
bottom = top + cellSize
right = left+cellSize
flag_img = PhotoImage(file="flag.gif")
flag_label = Label(image = flag_img)
flag_label.image = flag_img
cake_img = PhotoImage(file = "cakeflag.gif")
cake_label = Label(image = cake_img)
cake_label.image = cake_img
canvas.create_rectangle(left,top, right, bottom, fill = 'gray')
if board[row][col] == -1:
if canvas.data['isGameOver'] == True:
