Python3 ValueError - 迭代列表時解包的值太多

Question

這是一個簡單的代碼，旨在使用英語名字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)

為了這篇文章，我把names變小了，但我包括了 100 個名字。

output：

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並遍歷列表的兩個切片

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

Answer 2

如果我得到你，這是解決方案；

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


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