在Python中,要寻找列表中元素的下标,你可以使用以下几种方法:
1. 使用`enumerate`函数:
```python
numbers = [10, 29, 30, 41]
for index, value in enumerate(numbers):
print('({0}, {1})'.format(index, value))
2. 使用列表推导式结合`enumerate`:
```python
word = ['dislike', ' is ', 'life', 'like', ' long ', 'python', 'short', 'too', ' is ']
word1 = [(i, x) for i, x in enumerate(word) if x == ' is ']
print(word1)
3. 使用`list.index()`方法查找特定元素的下标:
```python
name = ['hello', 'world', 'a', 'b', 'c', 1, 2, 3, 'hello', 'world', 'a', 'b', 'c', 1, 2, 3]
first_pos = 0
for i in range(name.count(2)):
new_list = name[first_pos:]
next_pos = new_list.index(2) + 1
print('find', first_pos, next_pos)
first_pos = next_pos
4. 使用`list.count()`方法结合循环查找所有特定元素的下标:
```python
name = ['hello', 'world', 'a', 'b', 'c', 1, 2, 3, 'hello', 'world', 'a', 'b', 'c', 1, 2, 3]
first_pos = 0
while first_pos < len(name):
pos = name.index(2, first_pos)
print('find', first_pos, pos)
first_pos = pos + 1
