If a python were to catch an impala, it is possible that hyenas could attempt to steal the kill. Hyenas are known to be bold and aggressive, and they will often work together in groups to overpower their prey or steal food from other predators. However, it is also possible that the python could successfully defend its kill, using its powerful muscles and constriction to keep the hyenas at bay.
In any case, interactions between different species in the wild can be unpredictable and dynamic, and the outcome of any given encounter will depend on a variety of factors, including the size and strength of the animals involved, the behavior and tactics of each species, and the availability of other food sources in the area.
