In that case you don't need a lambda:

import Tkinter as tk

class Test:
    def __init__(self, parent):
        buttons = [tk.Button(parent, text=str(x+1),
command=self.highlight(x)) for x in range(5)]
        for button in buttons:
            button.pack(side=tk.LEFT)

    def highlight(self, x):
        print "highlight", x

root = tk.Tk()
d = Test(root)
root.mainloop()

Bye,
