I have list with the following values:
numeros = [5, 3, 1, 2, 3, 4, 5, 5, 5]
In Python would have some function to count how many times some value repeats?
For example: I want to know how many times 5 has repeated.
Count the number of occurrences of a value in a list

Using Python 2 or 3
Only use the method count()
numeros = [5, 3, 1, 2, 3, 4, 5, 5, 5]
numeros.count(5)

You can use Counter :
import collections
numeros = [5, 3, 1, 2, 3, 4, 5, 5, 5]
repetidos = collections.Counter(numeros)
print(repetidos[5])
See running on ideone .
If you prefer the short form:
print(collections.Counter([5, 3, 1, 2, 3, 4, 5, 5, 5])[5])
