如何搜索二维列表并打印位置（x，y）

Question

I have this problem in my python class. I have to loop through a 2d list of items and print what is found and in what location (x, y).

Output that I should get:

In square (1, 0) we found apple
In square (4, 0) we found lion
In square (1, 1) we found kobra
In square (2, 1) we found cat
In square (3, 1) we found kobra
In square (0, 2) we found hyena
In square (2, 2) we found apple
In square (3, 2) we found kobra

The code I have so far:

ITEMS = {
    "a": "apple",
    "k": "kobra",
    "@": "cat",
    "h": "hyena",
    "l": "lion"
}
def inspect_square(square, y, x):
    while True:
        if square == "a":
            print("In square ({}, {}) we found {}".format(x, y, ITEMS[square]))
        elif square == "k":
            print("In square ({}, {}) we found {}".format(x, y, ITEMS[square]))
        elif square == "@":
            print("In square ({}, {}) we found {}".format(x, y, ITEMS[square]))
        elif square == "h":
            print("In square ({}, {}) we found {}".format(x, y, ITEMS[square]))
        elif square == "l":
            print("In square ({}, {}) we found {}".format(x, y, ITEMS[square]))
        else:
            continue


def search_field(field):
    for y in field:
        for x in y:
            inspect_square(square, y, x)



field = [
    [" ", "a", " ", " ", "l"],
    [" ", "k", "@", "k", " "],
    ["h", " ", "a", "k", " "]
]


search_field(field)

I get error message that square is not defined but I'm not sure if that's the main problem in my work so far. It might be a simple fix, but I can't see it. How can I continue? Is there a mistake?

Thanks in advance!

NameError: name 'square' is not defined

Answer 1

You get the error when calling the inspect_square . Because you call it with square which is not defined.

Another solution

for y, line in enumerate(field):
    for x, item in enumerate(line):
        if item != " ":
            print("In square ({}, {}) we found {}".format(x, y, ITEMS[item]))
