<｜begin▁of▁sentence｜>### Instruction:
Given various data types such as list, set, tuple, dictionary, and string, demonstrate how to retrieve an arbitrary element from each of these iterables using NetworkX's utility function arbitrary_element. Additionally, clarify what kind of error might occur if the iterable passed to the function is an iterator instead of an iterable.
### Response:
import networkx as nx

# List
result_list = nx.utils.arbitrary_element([1, 2, 3])
print('Arbitrary element from list:', result_list)

# Set
result_set = nx.utils.arbitrary_element({1, 2, 3})
print('Arbitrary element from set:', result_set)

# Tuple
result_tuple = nx.utils.arbitrary_element((1, 2, 3))
print('Arbitrary element from tuple:', result_tuple)

# Dict
sample_dict = {k: v for k, v in zip([1, 2, 3], [3, 2, 1])}
result_dict = nx.utils.arbitrary_element(sample_dict)
print('Arbitrary element from dict keys:', result_dict)

# Dict Values
dict_values = sample_dict.values()
result_dict_values = nx.utils.arbitrary_element(dict_values)
print('Arbitrary element from dict values:', result_dict_values)

# String
result_str = nx.utils.arbitrary_element('hello')
print('Arbitrary element from string:', result_str)
