在同一索引的嵌套列表中查找最小的数字

Question

I have a list of products:

list = [['product 1', 2.4, 322], ['product 2', 5.35, 124], ['product 3', 8.41, 521]]

How can I loop through the list to find the product with lowest number at the index [1]?

Answer 1

You can use a key for min :

min(data, key=lambda p: p[1])

Answer 2

product = min(list, key=lambda item: item[1])[2]

Do not use list as a variable name, since list already refers to a list constructor.

Answer 3

You can use an external variable. And if any value is less than that you simply replace the array.

data = [['product 1', 2.4, 322], ['product 2', 5.35, 124], ['product 3', 8.41, 521]]

min_arr = data[0]
for arr in data:
    min_arr = arr if arr[1] < min_arr[1] else min_arr

print(min_arr)

#Output
['product 1', 2.4, 322]
