how to compare two strings in python while one of the two stings are taken from gui i/p?

import easygui     
count = 0
dish = easygui.enterbox("enter your favourite dish:")
with open("menu.txt") as f:
      content = f.readlines()
      for item1 in content:
            if item1 == dish :
                  easygui.msgbox("order taken.thankyou")
                  count = count + 1
            continue
      if count == 0 :
                  easygui.msgbox("plz order some other item")

my menu.txt is:

apple 

banana

orange

grape

mango

my input in gui(enterbox) is :

orange
