I have a small question with list in Python. I have a like like that x = [15,10,2,84,1,2,4,8] and I run the code x.index(x.count(x[0])). the result is 4 because the index of 1 is 4. however i don't know how comes 1 because 0 doesn't appear in the list. Similarly, I try 6, it doesn't appear in the list but the output of print(x.count) still 1. I don't know how it works.
