[Tutor] Converting ascii string to hex?

[Terry Carroll]

Is there a straightforward way to convert an ascii string to printable 
hexadecimal?

I've kludged up this, but there has to be a cleaner way:

>>> def asctohex(string_in):
...     a=""
...     for x in string_in:
...         a = a + (hex(ord(x)))[2:4]
...     return(a)
...
>>> print asctohex("a 1")
612031
>>>
