# 示例代码：打印字典

# 定义一个字典
my_dict = {
    'name': 'Alice',
    'age': 25,
    'city': 'Beijing'
}

# 方法1：直接打印整个字典
print("方法1：直接打印整个字典")
print(my_dict)
# 输出: {'name': 'Alice', 'age': 25, 'city': 'Beijing'}

# 方法2：逐项打印字典的键和值
print("\n方法2：逐项打印字典的键和值")
for key, value in my_dict.items():
    print(f"{key}: {value}")
# 输出:
# name: Alice
# age: 25
# city: Beijing

# 方法3：只打印字典的键
print("\n方法3：只打印字典的键")
for key in my_dict.keys():
    print(key)
# 输出:
# name
# age
# city

# 方法4：只打印字典的值
print("\n方法4：只打印字典的值")
for value in my_dict.values():
    print(value)
# 输出:
# Alice
# 25
# Beijing
