how to align text to the left?

please help to fix the script.

from tkinter import *
colors = ['red',  'white',  'blue']

def packbox(root):
    Label(root, text='Pack').pack()
    for color in colors:
        row = Frame(root)
        lab = Label(row, text=color, relief=RIDGE,  width=25)
        ent = Entry(row, bg=color,   relief=SUNKEN, width=50)
        row.pack(side=TOP,   expand=YES, fill=BOTH)
        lab.pack(side=LEFT,  expand=YES, fill=BOTH)
        ent.pack(side=RIGHT, expand=YES, fill=BOTH)

root = Tk()
packbox(root)
mainloop()

I would like to align the text in the Label widget on the left edge

Try this

Label(root, text='Pack', anchor='w').pack(fill='both')
