How does the itertools.islice() function differ from using generator[start:end] slicing?
They are equivalent in functionality
itertools.islice() can be used for any iterable, while slicing is specific to generators
generator[start:end] can be used for any iterable, while itertools.islice() is specific to generators
itertools.islice() modifies the original generator, while slicing creates a new generator
Answer: Option
Explanation:
itertools.islice() can be used for any iterable, not just generators, while slicing with generator[start:end] is specific to generators and creates a new generator. 
import itertools

def my_generator():
    for i in range(10):
        yield i

# Using itertools.islice() for slicing
sliced_iterable = itertools.islice(my_generator(), 2, 7)

for value in sliced_iterable:
    print(value)
