Functions:\n\
\n\
-hex(arg) -- Returns the hexadecimal representation of an integer\n\
-oct(arg) -- Returns the octal representation of an integer\n\
+ascii(arg) -- Returns the canonical string representation of an object.\n\
+filter(pred, iterable) -- Returns an iterator yielding those items of \n\
+ iterable for which pred(item) is true.\n\
+hex(arg) -- Returns the hexadecimal representation of an integer.\n\
+map(func, *iterables) -- Returns an iterator that computes the function \n\
+ using arguments from each of the iterables.\n\
+oct(arg) -- Returns the octal representation of an integer.\n\
+zip(iter1 [,iter2 [...]]) -- Returns a zip object whose .next() method \n\
+ returns a tuple where the i-th element comes from the i-th iterable \n\

The typical usage of this module is to replace existing builtins in a\n\
module's namespace:\n \n\
