Why does the hash function on two different objects return the same value?

Question

I used Spyder, launched Python 2.7.

Just found interesting things:

• hash (-1) and hash (-2) both return -2, is there a problem? I, although the hash function on another object should return different values. I read the previous posts that -1 is reserved as an error in Python.
• hash ('s') returns 1835142386, then the hash (1835142386) returns the same value. Is this another problem?

Thank.
