Even more succinctly:
def ishex(s):
return all(c in string.hexdigits for c in s)
I'll see your two-liner and raise you. :-)
ishex = lambda s: all(c in string.hexdigits for c in s)
I'see your one-liner and raise you by four characters :o)
ishex1 = lambda s: all(c in string.hexdigits for c in s) # Yours
ishex2 = lambda s: not(set(s)-set(string.hexdigits)) # Mine
I raise you one character:
ishex2 = lambda s: not(set(s)-set(string.hexdigits)) # Yours
ishex3 = lambda s: not set(s)-set(string.hexdigits) # Mine
I could actually go three better:
ishex3=lambda s:not set(s)-set(string.hexdigits)
:-)
ishex4=lambda s:not s.strip(string.hexdigits)
Doh!
