python (1,2,3)

# 创建一个元组
my_tuple = (1, 2, 3)

# 访问元组中的元素
print(my_tuple[0])  # 输出: 1

# 尝试修改元组（这将引发错误）
# my_tuple[0] = 4  # TypeError: 'tuple' object does not support item assignment

# 元组解包
a, b, c = my_tuple
print(a, b, c)  # 输出: 1 2 3

# 函数返回多个值
def get_values():
    return 1, 2, 3

values = get_values()
print(values)  # 输出: (1, 2, 3)

# 使用zip函数组合多个序列
names = ['Alice', 'Bob', 'Charlie']
ages = [24, 27, 22]
combined = list(zip(names, ages))
print(combined)  # 输出: [('Alice', 24), ('Bob', 27), ('Charlie', 22)]

# 错误的尝试
try:
    my_tuple[0] = 4
except TypeError as e:
    print(e)  # 输出: 'tuple' object does not support item assignment

# 正确的做法
new_tuple = (4,) + my_tuple[1:]
print(new_tuple)  # 输出: (4, 2, 3)
