How to shorten the size of program

[garikhgh0]

hi there.
I have created a tictactoe game for two players (X and 0) and made it executable, after which it became 15 Mb which is more for such a game. How can I shorten it?

I have not removed the whitespaces maybe they are the reason?

write more efficient code?
Hard to say without seeing your code.

[garikhgh0]

Maybe the white spaces the reason!!!

You haven't posted any code.

from tkinter import *
def callback(r,c):
  global player
  if player == 'X' and states[r][c] == 0 and stop_game==False:
    b[r][c].configure(text='X', fg='blue', bg='white')
    states[r][c] = 'X'
    player = 'O'
  if player == 'O' and states[r][c] == 0 and stop_game==False:
    b[r][c].configure(text='O', fg='orange', bg='black')
    states[r][c] = 'O'
    player = 'X'
  check_for_winner()
  
def check_for_winner():
  global stop_game
  for i in range(3):
    if states[i][0]==states[i][1]==states[i][2]!=0:
      b[i][0].configure(bg='grey')
      b[i][1].configure(bg='grey')
      b[i][2].configure(bg='grey')
      stop_game = True
  for i in range(3):
    if states[0][i]==states[1][i]==states[2][i]!=0:
      b[0][i].configure(bg='grey')
      b[1][i].configure(bg='grey')
      b[2][i].configure(bg='grey')
      stop_game = True
      
  if states[0][0]==states[1][1]==states[2][2]!=0:
    b[0][0].configure(bg='grey')
    b[1][1].configure(bg='grey')
    b[2][2].configure(bg='grey')
    stop_game = True
    
  if states[2][0]==states[1][1]==states[0][2]!=0:
    b[2][0].configure(bg='grey')
    b[1][1].configure(bg='grey')
    b[0][2].configure(bg='grey')
    stop_game = True
    
root = Tk()
b = [[0,0,0],
     [0,0,0],
     [0,0,0]]
     
states = [[0,0,0],
          [0,0,0],
          [0,0,0]]
          
for i in range(3):
  for j in range(3):
    b[i][j] = Button(font=('Verdana', 56), width=3, bg='yellow',
    command = lambda r=i,c=j: callback(r,c))
    b[i][j].grid(row = i, column = j)

player = 'X'
stop_game = False
mainloop()

Import just what you need for the program.
For example:

In [1]: import urllib

In [2]: page = urllib.request.urlopen('http://python-forum.io')

In [3]: html = page.read()

Here I import the whole urllib module. But I am using only urlopen method. I do not need all the rest.
So it becomes:

In [1]: from urllib.request import urlopen

In [2]: page = urlopen('http://python-forum.io')

In [3]: html = page.read()

@wavic: the module is always fully imported, so there is no difference between the two.

Hah! Really?! What I am thinking I had to know that Thank you! Something new and important I learned today.

It is highly unlikely that whitespaces contribute anything significant to the program size. Let me turn the question around: why does it matter that your executable is 15MB? That's still a very small executable by modern standards.

---

If you're still interested in knowing why your executable is 15MB, I want to propose an experiment: strip out all the code, leaving behind something skeletal like:

from tkinter import *

print 'this is a pretty small script'

Now make a standalone executable out of this and see how large that is. I suspect that it'll be pretty close to 15MB (I haven't checked this myself, so I might be wrong).

Another experiment would be to repeat the above process after stripping out the import. I suspect that the answer to those questions would demonstrate that your code contributes little to the size of your standalone executable's size.

and made it executable, after which it became 15 Mb which is more for such a game.

C:\1\exe_env
λ pyinstaller tk_test.py --onefile --windowed --clean

Makes working one file tx_test.exe of size 7.1 MB.
