這有點老套，但是如果這是您經常要做的事情，您可以使用readline模塊和函數修飾符。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)

可以將這些類添加到PYTHONSTARTUP文件中，這樣每次加載解釋器時，都可以使用它們。在

^{pr2}$

我已經為自己創建了一個自定義的PS1(在PYTHONSTARTUP文件中)，它顯示了當前的readline歷史編號，這意味著我可以快速地將其添加到@saved_function參數列表中，這比使用readline.get_current_history_length函數獲取它要容易得多：[508] @SavedFunction(509)

(509) def foo(bar):

(510) print(bar)

[511] print(foo)

def foo(bar):

print(bar)
