Answer 1

我还使用 see，它是 Python 目录的更简单的替代品。

from see import see

使用 see 而不是 dir 的示例如下：

>>> k = {}
>>> dir(k)
['__class__', '__cmp__', '__contains__', '__delattr__', '__delitem__','__doc__',
'__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__gt__',
'__hash__', '__init__', '__iter__', '__le__', '__len__', '__lt__', '__ne__',
'__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__',
'__setitem__', '__sizeof__', '__str__', '__subclasshook__', 'clear', 'copy',
'fromkeys', 'get', 'has_key', 'items', 'iteritems', 'iterkeys', 'itervalues',
'keys', 'pop', 'popitem', 'setdefault', 'update', 'values']
>>> see(k)
    []              in              <               <=              ==
    !=              >               >=              hash()          help()
    iter()          len()           repr()          str()           .clear()
    .copy()         .fromkeys()     .get()          .has_key()      .items()
    .iteritems()    .iterkeys()     .itervalues()   .keys()         .pop()
    .popitem()      .setdefault()   .update()       .values()

Answer 2

# Add auto-completion and a stored history file of commands to your Python
# interactive interpreter. Requires Python 2.0+, readline. Autocomplete is
# bound to the Esc key by default (you can change it - see readline docs).
#
# Store the file in ~/.pystartup, and set an environment variable to point
# to it:  "export PYTHONSTARTUP=/home/user/.pystartup" in bash.
#
# Note that PYTHONSTARTUP does *not* expand "~", so you have to put in the
# full path to your home directory.

import atexit
import os
import readline
import rlcompleter

readline.parse_and_bind("tab: complete")
historyPath = os.path.expanduser("~/.history.py")

def save_history(historyPath=historyPath):
    import readline
    readline.write_history_file(historyPath)

if os.path.exists(historyPath):
    readline.read_history_file(historyPath)

atexit.register(save_history)
del os, atexit, readline, rlcompleter, save_history, historyPath
