Question

I have written this code and in this the function gen() id used to generate numbers at random for sorting. My code is like

from Tkinter import *
import random

class Sorting( Frame ):
   def __init__( self ):
      Frame.__init__( self )

      self.master.title( "Sorting" )
      self.master.rowconfigure( 5, weight = 1 )
      self.master.columnconfigure( 5, weight = 1 )
      self.grid( sticky = W+E+N+S )

      #label for sort intro      
      self.label1 = Label( self, text = "Select Sort", width = 25 , height=2)
      self.label1.grid( row = 0, column = 1, sticky = N )

      #Radio buttons for sorts
      self.button1 = Radiobutton( self, text = "Bubble Sort" )
      self.button1.grid( row = 1, column = 0, sticky = W+E+N+S )

      self.button2 = Radiobutton( self, text = "Quick Sort" )
      self.button2.grid( row = 1, column = 1, sticky = W+E+N+S )

      self.button3 = Radiobutton( self, text = "Shell Sort" )
      self.button3.grid( row = 1, column = 2, sticky = W+E+N+S )

      #label to store value
      def gen():
         for x in range(0,10):
            num=random.randint(0,100)
            self.label2 = Label( self,text='%s'%num, width = 2, height = 2 )
            self.label2.grid( row =3 , columnspan =10 , sticky = W+E+N+S )

      #button to generate number
      self.button4 = Button( self,text='Generate no.', command=gen )
      self.button4.grid( row = 2,column=1, sticky = W+E+N+S )
      self.rowconfigure( 5, weight = 1 )
      self.columnconfigure( 5, weight = 1 )

def main():
   Sorting().mainloop()   

if __name__ == "__main__":
   main()

I want to use it for generating random numbers and then sorting them. Any suggestion to do it.

Try this:

  #label to store value
  def gen():
      self.nums = []
      for x in range(0, 10):
          self.nums.append(random.randint(0, 100))
      # . . . . . . . . . .  .    <- maybe here call sorting method on self.nums
      num = ''.join('%4i' % num for num in self.nums)
      self.label2 = Label( self, text=num, width=2, height=2)
      self.label2.grid(row=3, columnspan=10, sticky=W+E+N+S)

The values to sort are stored in self.nums. You want to call your sorting algorithm to that list before showing them in the label.

I tried to keep your code as it was as much as possible. From this point it can be further optimized. For example, you could substitute:

  self.nums = []
  for x in range(0, 10):
      self.nums.append(random.randint(0, 100))

with

  self.nums = [random.randint(0, 100) for x in range(10)]
