By default, a Pandas index is a series of integers ascending from 0, similar to the indices of Python arrays. However, indices can use any NumPy data type, including floating point, timestamps, or strings.

APL allows setting the index origin to 0 or 1 during runtime programmatically. [9] [10] Some recent languages, such as Lua and Visual Basic, have adopted the same convention for the same reason.
