命名2D数组的最佳Python数据结构是什么

Question

I am new to Python. I have two dimensional data. Lets say "Brand" and "Respondent". I want to perform some calculations on this data. For each brand and respondent there is a corresponding rating. ie:

Pepsi -> Respondent 1 -> 8 Coke -> Respondent 3 -> 10

I could store this in a 2D list, but I like to retain the references for the brands and respondent number/name somehow.

What is the best data structure for this? Perhaps I could look them up as:

random_data["Pepsi"][123]

or iterate through each respondent and do some math on each brand.

Answer 1

It depends on what you need to do with the data, dictionaries are a good start:

mydict = {"Pepsi": {"respondent": 3, "rating": 8}, "Coke": {"respondent": 3, "rating":10}}

You can access it using:

mydict["Pepsi"]["rating"]
