# Python 将元组解包为变量或参数 > 原文： [https://howtodoinjava.com/python/unpack-tuple-sequence/](https://howtodoinjava.com/python/unpack-tuple-sequence/) Python 示例将 N 元素元组或序列解包为 N 个变量的集合。 Python 示例**将元组解包为变量**。 ## 1\. Python 解包元组示例 可以使用简单的赋值操作将任何序列（或可迭代）解包为变量。 唯一的要求是变量和结构的**数量与序列**匹配。 #### 1.1 解包示例 – 1 ```py >>> data = (1, 2, 3) >>> x, y, z = data >>> x 1 >>> y 2 >>> z 3 ``` #### 1.2 解包示例 – 2 ```py >>> data = [ 'Lokesh', 37, 73.5, (1981, 1, 1) ] >>> name, age, weight, dob = data >>> name 'Lokesh' >>> dob (1981, 1, 1) # Another Variation >>> name, age, weight, (year, mon, day) = data >>> name 'Lokesh' >>> year 1981 >>> mon 1 >>> day 1 ``` #### 1.3 解包示例 – 3 ```py >>> greeting = 'Hello' >>> a, b, c, d, e = greeting >>> a 'H' >>> b 'e' >>> c 'o' ``` ## 2.解包时可能出现的错误 如果元素的数量**不匹配**，则会出现错误。 ```py >>> p = (4, 5) >>> x, y, z = p Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: need more than 2 values to unpack ``` 学习愉快！
