python - How to find specific word in a text file? -

i know how find specific word in text file without maybe using module re. current code:

searchfile = open("menu.txt", "r") mylist = [] cho = input("what cusine view menu for")   line in searchfile:     mylist.append(line+"\n")  splitted_line = line.split(',') print(splitted_line[0]) indian = (mylist[0]) mexican = (mylist[1]) italian = (mylist[2])  if 'mexican' in cho:     print(mexican) elif 'indian' in cho:     print(indian) elif 'italian' in cho:     print(italian)   searchfile.close()  cho2 = input("would order or wait till later") if cho2 == 'now':     import practiseassessment.py  if cho2 == 'later':     print("ok more information contact hungry horse @ 07969214142") 

this text file:

lamb curry , indian , chicken curry , indian vegtable curry , indian  tacos , mexican fajitas , mexican nachos , mexican margherita pizza , italian vegetable pizza , italian bbq chicken pizza , italian 

i want print indian food when cho == indian. want text file new line every dish

this 1 way approach problem. can see, can python's builtin strings.

note use str.lower().strip() normalize search terms , menu items before comparing them. give more generous results , not punish users inputting spaces, , thing.

# first parse input file , create menu list open("food.txt", "r") foodfile:     menu_items = ' '.join(foodfile.readlines()).strip().split(',') menu_items = [item.strip() item in menu_items]  # menu_items list ['lamb curry', 'indian', 'chicken curry' ... etc  # made next part loop, can test several search terms. # instead of searching on user input, can split menu several lists # in real world cases not useful. approach # users can search "pizza" or "chicken" in addition "mexican", "italian" etc.   while true:     cho = input("what cusine view menu for? ").lower().strip()     if not cho:           break  # break loop if user submits empty search string     search_results = [food food in menu_items if cho in food.lower()]     print('\nfound %d items on meny matching "%s"' % (len(search_results), cho))     print(', '.join(search_results))  print('\ngoodbye')  

example output:

what cusine view menu for? indian

found 3 items on meny matching "indian" indian, indian vegtable curry, indian tacos

what cusine view menu for? mexican

found 3 items on meny matching "mexican" mexican fajitas, mexican nachos, mexican margherita pizza

what cusine view menu for? pizza

found 3 items on meny matching "pizza" mexican margherita pizza, italian vegetable pizza, italian bbq chicken pizza
