Functions:\n\
|
|
\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\
|
|
argument.\n\
|
|
\n\

The typical usage of this module is to replace existing builtins in a\n\

|
module's namespace:\n \n\

from future_builtins import ascii, filter, map, hex, oct, zip\n");
