それモジュールで

Python

慣習に従わないことによる弊害というものは理解しにくいものかな。
てか、やるならもう少しうまいやり方があるだろう。

typealias.py

Str = str
List = list
Dict = dict
Tuple = tuple
Set = set
Object = object
Type = type
Int = int
Long = long
Float = float
Complex = complex
Bool = bool
Unicode = unicode
File = file

あとまぁ、typealias.py はこんなのでもいいかもしれない。

import __builtin__

def _init():
    types = []

    context = globals()
    for name in dir(__builtin__):
        obj = getattr(__builtin__, name)
        if type(obj) is type and name.islower():
            capitalized = name.capitalize()
            context[capitalized] = obj
            types.append(capitalized)

    global __all__
    __all__ = types

_init()
