Search Function Python using 2D array list

I am trying to do a search function for a 2 dimension array or list. How do I search thru this list and return the values of the items.

myfoodlist = [("Chicken Pasta", 10),("Beef Noodle", 12),("Hot Coffee", 4.20),( "Fish and Chips", 8.50)]

foodsearch = raw_input("Please input food to search: ")

        for item in (myfoodlist) :

            if item.find(foodsearch) != -1:
                searchReturnsItems.append(item)
        for item in searchReturnsItems:
            print(item, "\t:\t")
        searchReturnsItems.clear()

Example

I like to ask for a key word like "beef" and return a list of all beef items and store in array.

Above is my code and I have some challenges.

Anyone can provide me an example to search a 2D array will be helpful

myfoodlist = [("Chicken Pasta", 10),("Beef Noodle", 12),("Hot Coffee", 4.20),( "Fish and Chips", 8.50)]

foodsearch = input("Please input food to search: ")

def searchFood():

        for item in (myfoodlist) :

            if(item[0]==foodsearch):

                return item[0],item[1]
searchFood()

output

Please input food to search: Hot Coffee

Out[2]: ('Hot Coffee', 4.2)

I've slightly modified your searching method to use list comprehension, and use re package to support partial case insensitive searches.

import re

myfoodlist = [("Chicken Pasta", 10),("Beef Noodle", 12),("Hot Coffee", 4.20),( "Fish and Chips", 8.50)]

foodsearch = input("Please input food to search: ")

searchReturnsItems = [item for item in myfoodlist if re.search(foodsearch, item[0], re.IGNORECASE)]

for item in searchReturnsItems:
    print(item, "\t:\t")
searchReturnsItems.clear()

Output

Please input food to search: beef
('Beef Noodle', 12)
