vastorbit.VastFrame.empty¶

VastFrame.empty() → bool¶

Returns True if the VastFrame is empty.

Returns:: True if the VastFrame has no VastColumns.
Return type:: bool

Examples

Let’s begin by importing vastorbit.

import vastorbit as vo

Hint

By assigning an alias to vastorbit, we mitigate the risk of code collisions with other libraries. This precaution is necessary because vastorbit uses commonly known function names like “average” and “median”, which can potentially lead to naming conflicts. The use of an alias ensures that the functions from vastorbit are used as intended without interfering with functions from other libraries.

Let us create a dummy dataset and check:

vdf = vo.VastFrame({"val": [0, 10, 20]})

	123 val Integer
1	0
2	10
3	20

Rows: 1-3 | Column: val | Type: integer

Let’s check if it is empty:

vdf.empty()
