这有点老套，但是如果这是您经常要做的事情，您可以使用readline模块和函数修饰符。在class PrintableFunction(object):

"""A class that contains a function and its start and end points

in the readline history"""

def __init__(self, func, start, end):

self.start = start

self.end = end

self.func = func

def __call__(self, *args):

self.func(*args)

def __str__(self):

"""Just get all the readline history lines from start to end and

return them"""

lines = []

for i in range(self.start, self.end + 1):

lines.append(readline.get_history_item(i))

return "\n".join(lines)

class SavedFunction(object):

"""The actual function decorator. It takes one argument, the history

line that at which the function definition will begin."""

def __init__(self, start):

"""Take the starting line as an argument to the decorator. The end

line is grabbed from the current history after the function has

been entered"""

self.start = start

self.end = readline.get_current_history_length()

def __call__(self, func):

return PrintableFunction(func, self.start, self.end)

可以将这些类添加到PYTHONSTARTUP文件中，这样每次加载解释器时，都可以使用它们。在

我已经为自己创建了一个自定义的PS1(在PYTHONSTARTUP文件中)，它显示了当前的readline历史编号，这意味着我可以快速地将其添加到@saved_function参数列表中，这比使用readline.get_current_history_length函数获取它要容易得多：[508] @SavedFunction(509)

(509) def foo(bar):

(510) print(bar)

[511] print(foo)

def foo(bar):

print(bar)
