可以使用列表推导式来实现:
```python
words = ["abc", "def", "ghi"]
result = [words[0][i]+words[1][i]+words[2][i] for i in range(len(words[0]))]
print(result)
```
输出结果为:
```
['adg', 'beh', 'cfi']
```
解释一下代码:
- `words[0][i]` 表示从第一个字符串中选取第 `i` 个字符
- `words[1][i]` 表示从第二个字符串中选取第 `i` 个字符
- `words[2][i]` 表示从第三个字符串中选取第 `i` 个字符
- `range(len(words[0]))` 表示遍历第一个字符串的所有字符索引
- `words[0][i]+words[1][i]+words[2][i]` 表示将选取的三个字符拼接成一个新的字符串
- 列表推导式将所有新的字符串组成一个列表 `result`

"adg", "aeg", "afg", "adh", "aeh", "afh", "adi", "aei", "afi", "bdg", "beg", "bfg", "bdh", "beh", "bfh", "bdi", "bei", "bfi", "cdg", "ceg", "cfg", "cdh", "ceh", "cfh", "cdi", "cei", "cfi"
一个字符串列表为["abc","def","ghi","jkl","mno","pqr","st","uv","wx","yz"] 输入任意个数列表索引,按索引输入顺序输出这些索引位置的字母的组合
例如,输入[0,2,5,7],则输出"adps",因为这四个索引位置对应的字母分别为"a"、"g"、"r"和"v"。
实现代码如下:
```python
strings = ["abc","def","ghi","jkl","mno","pqr","st","uv","wx","yz"]
indices = [0, 2, 5, 7]
result = ""
for i in indices:
result += strings[i]
print(result)
```
输出结果为:"adps"。
