The built-in slice() function creates a slice object representing a set of indices specified by range(start, stop, step). This object can be used to extract portions of sequences like strings, lists, or tuples:
slice() Signatures Arguments Argument Description Default Value start The initial index of the slice. None (start of the sequence) stop The ending index of the slice, exclusive. Required argument step The step between each index in the slice. None (step of 1) Return Value

With only a stop value:
With start, stop, and step values:
slice() Common Use Cases
The most common use cases for the slice() function include:
slice() Real-World Example
Say that you have a list of daily temperatures and want to extract only the temperatures for the first day of each week, skipping weekends:
In this example, slice(0, None, 7) allows you to select every 7th temperature starting from the first element, effectively picking temperatures for the first day of each week.
