This is one way to approach the problem. As you can see, you can do everything with python’s builtin strings. <\/p>\n

Note that use str.lower().strip()<\/code> to normalize the search terms and the menu items before comparing them. That will give more generous results and not punish users for inputting extra spaces, and is usually a good thing.<\/p>\n

# First parse you input file and create the menu list\nwith open(\"food.txt\", \"r\") as foodfile:\n    menu_items=\" \".join(foodfile.readlines()).strip().split(',')\nmenu_items = [item.strip() for item in menu_items]\n\n# menu_items is now the list ['lamb curry', 'indian', 'chicken curry' ... etc\n\n# I made the next part into a loop, so you can test several search terms.\n# instead of searching on user input, you can split the menu into several lists\n# but in most real world cases that is not really useful. With this approach\n# users can search for \"pizza\" or \"chicken\" in addition to \"mexican\", \"italian\" etc. \n\nwhile True:\n    cho = input(\"What cusine would you like to view the menu for? \").lower().strip()\n    if not cho:  \n        break  # break the loop if user submits an empty search string\n    search_results = [food for food in menu_items if cho in food.lower()]\n    print('\\nFound %d items on the meny matching \"%s\"' % (len(search_results), cho))\n    print(', '.join(search_results))\n\nprint('\\ngoodbye') \n<\/code><\/pre>\n
example output:<\/p>\n
\n
What cusine would you like to view the menu for? indian<\/strong><\/p>\n
Found 3 items on the meny matching “indian” indian, indian vegtable
\n  curry, indian tacos<\/p>\n
What cusine would you like to view the menu for? mexican<\/strong><\/p>\n
Found 3 items on the meny matching “mexican” mexican fajitas, mexican
\n  nachos, mexican margherita pizza<\/p>\n
What cusine would you like to view the menu for? pizza<\/strong><\/p>\n
Found 3 items on the meny matching “pizza” mexican margherita pizza,
