如何在python中访问字典的第二个元素？

my_dict = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}
second_element = list(my_dict.items())[1]
print(second_element)

('key2', 'value2')

my_dict = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}
count = 0
for key, value in my_dict.items():
    count += 1
    if count == 2:
        second_element = (key, value)
        break
print(second_element)

('key2', 'value2')
