This page lists features that GvR has mentioned as goals for Python 3.0.
- Reduce feature duplication:
- string module vs. string methods
- xrange() vs range()
- int vs. long
- 8 bit vs. Unicode strings
- map/filter/reduce vs. list comprehensions
- lambda vs. def
- Library reorganization
- Return iterators instead of lists
- d.keys(), .values(), .items()
- range(), zip(), map(), filter()
- Consume iterators
- min(), max()
- Optional static typing?
- Support only new-style classes; classic classes will be gone.
Remove string exceptions, x for repr(x), sys.exc_type, coerce(), other deprecated stuff
- print as a function -- write(x,y,z), writeln(x,y,z)
See the "Python Regrets" talk and other recent presentations by Guido.
Rearrangements
intern(), id(): put in sys
xrange(): make range() return an iterator
buffer(): must die (use bytes, PEP 296)
raw_input(): use sys.stdin.readline()
input(): use eval(sys.stdin.readline())
callable(): just call it, already
execfile(), reload(): use exec()
compile(): put in sys
exec as a statement is not worth it -- make it a function
