Python3 ValueError -迭代列表时要解压缩的值太多

Question

这是一个简单的代码，用于使用英文名和姓氏列表生成全名列表：

names = """
Walter
Dave
Albert""".split()

fullnames = [(first + last) for first, last in names]
print(fullnames)

为了这篇文章，我把names变小了，但我收录了100个名字。

输出：

Traceback (most recent call last):
  File "/home/pussyslayer42069/Desktop/py/names.py", line 105, in <module>
    fullnames = [(first + last) for first, last in names]
  File "/home/pussyslayer42069/Desktop/py/names.py", line 105, in <listcomp>
    fullnames = [(first + last) for first, last in names]
ValueError: too many values to unpack (expected 2)

Answer 1

使用zip遍历列表的两个片段

[(f, l) for f, l in zip(names[:-1], names[1:]]

Answer 2

如果我找到你了，这就是解决方案；

names = """
Walter
Dave
Albert""".split()


fullnames = [(names[i] + ' ' + names[i + 1]) for i in range(len(names) - 1)]
print(fullnames)
