执行函数时放入python解释器

i have a python module with a function:

我有一个功能的python模块：

def do_stuff(param1 = 'a'):
    if type(param1) == int:
        # enter python interpreter here
        do_something()
    else:
        do_something_else()

is there a way to drop into the command line interpreter where i have the comment? so that if i run the following in python:

有没有办法进入命令行解释器，我有评论？所以，如果我在python中运行以下内容：

>>> import my_module
>>> do_stuff(1)

i get my next prompt in the scope and context of where i have the comment in do_stuff()?

我在do_stuff（）的评论范围和上下文中得到了我的下一个提示？

3 个解决方案

#1

Inserting

插入

import pdb; pdb.set_trace()

will enter the python debugger at that point

此时将进入python调试器

See here: http://docs.python.org/library/pdb.html

If you want a standard interactive prompt (instead of the debugger, as shown by prestomation), you can do this:

如果你想要一个标准的交互式提示（而不是调试器，如prestomation所示），你可以这样做：

import code
code.interact(local=locals())

See: the code module.

请参阅：代码模块。

If you have IPython installed, and want an IPython shell instead, you can do this for IPython >= 0.11:

如果你安装了IPython，并且想要一个IPython shell，你可以为IPython> = 0.11执行此操作：

import IPython; IPython.embed()

or for older versions:

或旧版本：

from IPython.Shell import IPShellEmbed
ipshell = IPShellEmbed()
ipshell(local_ns=locals())

#3

If you want a default Python interpreter, you can do

如果你想要一个默认的Python解释器，你可以这样做

import code
code.interact(local=dict(globals(), **locals()))

This will allow access to both locals and globals.

这将允许访问本地和全局。

If you want to drop into an IPython interpreter, the IPShellEmbed solution is outdated. Currently what works is:

如果要放入IPython解释器，IPShellEmbed解决方案已过时。目前有效的是：

from IPython import embed
embed()
