What would be the equivalent of find used in strings to use in lists? For example, if it is a=['a','b','c'], as return to position 1 of 'b'?

The method find, of string, returns the smallest index where the searched value is found. In lists, there is the method index:
>>> numeros = [1, 2, 3, 4, 5]
>>> numeros.index(3)
2
I mean, doing numeros.index(3) return the index where the number 3 is - remembering that the index starts at 0, so the third value will be at index 2.
If the value is not found, an exception ValueError will be launched.
>>> numeros = [1, 2, 3, 4, 5]
>>> numeros.index(9)
Traceback (most recent call last):
File "python", line 1, in <module>
ValueError: 9 is not in list

Thank you Anderson, and sorry for the elementary question.

@Brenofaria No need to apologize. Any doubt is valid.
