Human: Give me a Python code to iterator with index. Assistant: 
Here is a Python code to iterator with index

import itertools

def _iterator_with_index(iterator, index):
    """Returns iterator with index."""
    return ((i, j) for i, j in zip(iterator, list(range(index))))

# Enter the iterator
iterator = iter(list(range(10)))

# Enter the index
index = 5

# Calling the function
iterator_with_index = _iterator_with_index(iterator, index)

# Printing the result
for i, j in iterator_with_index:
    print((i, j))

#Example Output
# (0, 0)
# (1, 1)
# (2, 2)
# (3, 3)
# (4, 4)

#Remember to inspect code for bugs.
