Python (numpy) sort character order?

What is the sorting order of characters in Python (or numpy)? is there any table?

[In] : np.sort(["a","c","b","-"])
[Out]: array(['-', 'a', 'b', 'c'], 
       dtype='|S1')
[In] : np.sort(["a","c","b","78"])
[Out]: array(['78', 'a', 'b', 'c'], 
       dtype='|S1')

Is there anything which would sort after the letters? Or, alternately, how is this order decided? I tried a lot of special characters, they all sort in the front.

sorted()

behaves the same way.

The builtin ord() returns the value of an 8-bit character.

Try ord('a') etc.

In [1]: ord('a')
Out[1]: 97

In [2]: ord('&')
Out[2]: 38

chr(97) is the inverse of ord('a')

In [3]: table = {i: chr(i) for i in xrange(i)}

In [4]: table
...
