Python序列解包技巧详解

# 元组解包
t = (1, 2, 3)
a, b, c = t
print(a, b, c)  # 输出: 1 2 3
<h1>列表解包</h1><p>lst = [4, 5, 6]
x, y, z = lst
print(x, y, z)  # 输出: 4 5 6</p><h1>字符串解包</h1><p>s = "abc"
p, q, r = s
print(p, q, r)  # 输出: a b c</p>

# 将剩余元素打包成列表
nums = [1, 2, 3, 4, 5]
a, *b, c = nums
print(a)    # 1
print(b)    # [2, 3, 4]
print(c)    # 5
<h1>星号放在开头</h1><p>*x, y, z = [10, 20, 30, 40]
print(x)  # [10, 20]
print(y)  # 30
print(z)  # 40</p>

# 嵌套元组解包
data = ("Alice", (25, "Engineer"))
name, (age, job) = data
print(name)  # Alice
print(age)   # 25
print(job)   # Engineer
<h1>嵌套列表解包</h1><p>nested = [1, [2, 3], 4]
a, [b, c], d = nested
print(a, b, c, d)  # 1 2 3 4</p>

# 函数返回多个值（本质是返回元组）
def get_name_age():
    return "Bob", 30
<p>name, age = get_name_age()
print(name, age)  # Bob 30</p><h1>用 * 解包参数传递</h1><p>def add(a, b, c):
return a + b + c</p><p>values = [1, 2, 3]
result = add(*values)
print(result)  # 6</p>
