slice_pct
The slice_pct method returns a table that is a subset of another table corresponding to the difference between the start and end row percentages. For example, for a table of size 10, slice_pct(0.1, 0.7) will return a subset from the second row to the seventh row. Similarly, slice_pct(0, 1) would return the entire table (because row positions run from 0 to size - 1). If the percentage arguments are outside of the range [0.0, 1.0], an error will occur.
Attempting to use slice_pct on a blink table will raise an error.
Syntax
table.slice_pct(start_pct: float, end_pct: float) -> Table
Parameters
| Parameter | Type | Description |
|---|---|---|
| start_pct | float | The starting percentage point (inclusive) for rows to include in the result. The percentage arguments must be in the range [0.0, 1.0]. |
| end_pct | float | The ending percentage point (exclusive) for rows to include in the result. The percentage arguments must be in the range [0.0, 1.0]. |
Returns
A new table that is a subset of the source table.
Example
The following example filters the table to a subset between the tenth and 70th rows.
from deephaven import empty_table
source = empty_table(100).update(["X = i"])
result = source.slice_pct(0.1, 0.7)
- source
- result
