The Range function The built-in range function in Python is very useful to generate sequences of numbers in the form of a list. The given end point is never part of the generated list; range(10) generates a list of 10 values, the legal indices for items of a sequence of length 10.
Male kittens are usually neutered at between 4 to 6 months of age. However, the AVMA has endorsed early age neutering of dogs and cats 8 to 16 weeks of age. You and your vet can decide what is the best time starting in a few weeks.
It is best to wait until the kitten is 4-6 months old, although many vets will spay much earlier. Kittens should be spayed and neutered before they reach sexual maturity, whicâ¦h happens around 6 months old. The average age of spaying/neutering is about 4 months, but it can  be done as soon as 8 weeks, while some vets suggest to wait until  the kitten is 6 months old.
