我有两个包含应该连接在一起的值的字符串,这意味着string1中的值为1,string2中的值为2。这是我尝试过的代码:

答案 0 :(得分:2)
你可以使用zip
,它返回一个迭代器(在Python 2中只是一个列表),它会使用指定来源的值组合出来的元组:
str1 = 'John,Gabriel,Isaac,Albert'
str2 = 'Cena,Heins,Newton,Einstein'
for x, y in zip(str1.split(','), str2.split(',')):
print(x + y)
答案 1 :(得分:1)
要解决实际问题,请注意以下几行:
for x,y in str1.split(','),str2.split(','):
不代表你的意图。
有两件事正在发生。
for i in s:
迭代s
的元素,将它们分配给i
。在您的情况下s
是:
>>> str1.split(','),str2.split(',')
(['John', 'Gabriel', 'Isaac', 'Albert'], ['Cena', 'Heins', 'Newton', 'Einstein'])
即,一系列2个元素,每个元素都是一个列表。所以你的循环会迭代两次,每次都将i
设置为其中一个列表。
最重要的是,您还尝试解压缩i
,有效地尝试将x, y
分配给其中一个列表,与此相同:
>>> x, y = ['John', 'Gabriel', 'Isaac', 'Albert']
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: too many values to unpack
这不起作用,因为右侧的值比左侧的名称多。
解决方案是构造一个新序列,其中包含每个列表中的值对,并使用zip
对其进行迭代,正如其他人所说的那样。
答案 2 :(得分:1)
如果每个字符串中的字段数可能不同,您可以对Python 3使用itertools.zip_longest()
,或在Python 2中使用itertools.izip_longest()
:
from itertools import zip_longest
str1 = "John,Gabriel,Isaac,Albert,Aristotle"
str2 = "Cena,Heins,Newton,Einstein"
for firstname, surname in zip_longest(str1.split(','), str2.split(','), fillvalue=''):
print('{}{}{}'.format(firstname, ' ' if firstname and surname else '', surname))
输出:
John Cena Gabriel Heins Isaac Newton Albert Einstein Aristotle
否则,如果您确定名称始终是配对的,则可以使用zip()
。
