But that doesn’t really matter because the elements of a dictionary are never indexed with integer indices. Instead, you use the keys to look up the corresponding values: >>> print(eng2sp['two']) 'dos' The key'two'always maps to the value “dos” so the order of the items doesn’...

In this example code, even_items() uses a list comprehension rather than a for loop to extract every item from the list whose index is an even number.You can verify that even_items() works as expected by getting the even-indexed items from a range of integers from 1 to 10. The ...
Each vector embedding should have a path to the relevant vector field in your items being stored, a supported data type (float32, int8, uint8), the vector's dimensions, and the distance function being used for that embedding. Vectors indexed with the flat index type can be at most 505 ...
