python tuple转dict

# 示例元组
tuple_data = (('a', 1), ('b', 2), ('c', 3))

# 转换为字典
dict_data = dict(tuple_data)

print(dict_data)  # 输出: {'a': 1, 'b': 2, 'c': 3}

# 示例元组
tuple_data = (('key1', 'value1'), ('key2', 'value2'), ('key3', 'value3'))

# 使用字典推导式转换为字典
dict_data = {key: value for key, value in tuple_data}

print(dict_data)  # 输出: {'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}

try:
    tuple_data = (('a', 1), ('b', 2), ('c'))  # 最后一个元素只有一个值
    dict_data = dict(tuple_data)
except ValueError as e:
    print(f"Error: {e}")

tuple_data = (('a', 1), ('b', 2), ['c', 3])  # 第三个元素是列表而不是元组

# 使用断言确保每个元素都是元组
assert all(isinstance(item, tuple) and len(item) == 2 for item in tuple_data), "Invalid tuple data"

dict_data = dict(tuple_data)
