How can i get the index of a single value in mutiple list

s=[[‘1’,‘4’],[‘2’,‘3’]]

Here , how can i get the index of ’ 4 ’

```
for x in s:
for index, value in enumerate(x):
if value == '4':
print(index)
```

`s[0][1]`

You access the first list `0`

, and the second element inside that first list `1`

.

To get the index of ‘4’ or any other element , here is the code

```
for x,y in enumerate(s):
for index, value in enumerate(y):
if value == '4':
print(x,index)
```

The position of ‘4’ is 0,1 which means it is at ist position in 0th element.

Example:

- the index of ‘4’ = s[0].index(‘4’) = 1
- the index of ‘3’ = s[1].index(‘3’) = 2
- the index of [‘1’, ‘4’] = s.index([‘1’, ‘4’]) = 0

In general:

the index of an item x in a list a_list is: a_list.index(x)
