python - 使用python将每个字符串列表的最后一个字符加倍

Question

我有这个列表:

list1 = ["happy","sad","love","bad"]

我想复制每个单词的最后一个字符，它应该是这样的:

list2 = ["happyy","sadd","lovee","badd"]

我试过这个:

list1 = ["happy","sad","love","bad"]
l = len(list1)-1
ls = len(list1[l])-1
list2 = []
k=0
i=0
for k in list1[l]:
   for i in list1[ls]:
       list2.append(list1[l]+list1[ls-1])
print(list2)

我明白了:

['badsad', 'badsad', 'badsad', 'badsad', 'badsad', 'badsad', 'badsad', 'badsad', 'badsad', 'badsad', 'badsad', 'badsad']

Answer 1

在 Python 中，您可以使用切片来执行此操作。

list1 = ["happy","sad","love","bad"]
list2 = []
for l in list1:
    list2.append(l+l[-1])

print(list2)
