Imported CSV Data - Working with arrays and dictionary

I am working with a large CSV file containing following data:
DataID1234,72.819595,14.407141 ... ... ...

I managed to import the CSV file into an array giving this console output:
["DataID123", "73.075584", "12.631215"]

The array is accessible via data[1][1] // [73.07558]

I want to search the array by the dataID (e.g. “DataID1234”) and give back the values contained in column 2.

  1. Is there a way to get this done without a dictionary?

  2. How would I set up the dictionary?
