The slice() function in Python returns a slice object that represents a section of a sequence (such as a list, string, or tuple). It takes three optional parameters: start, stop, and step. This function is often used to extract a specific portion of a sequence without modifying the original data.
Parameter Values
| Parameter | Description |
|---|---|
| start | The starting index for the slice. This parameter is optional and defaults to None if not provided. |
| stop | The ending index for the slice. This parameter is required. |
| step | The step value for slicing. This parameter is optional and defaults to None if not provided. |
Return Values
The slice() function returns a slice object representing a set of indices.
How to Use slice() in Python
Return a slice object from start to stop with the specified step
slice_obj = slice(1, 10, 2)
result = some_list[slice_obj]Slice object can be used to retrieve specific elements from a sequence
slice_obj = slice(2, None)
result = some_list[slice_obj]Slice object can be used with the 'slice' notation to extract a portion of a sequence
slice_obj = slice(None, 5)
result = some_list[slice_obj]
