我怎么能做一个“如果从ipython运行”用Python测试？ [英] How can I do an "if run from ipython" test in Python?

问题描述

为了简化Ipython的调试，我在脚本开头包含以下内容

To ease debugging from Ipython, I include the following in the beginning of my scripts

from IPython.Debugger import Tracer
debug = Tracer()

但是，如果我从命令行启动我的脚本

However, if I launch my script from the command line with

$ python myscript.py

我收到与Ipython相关的错误。是否有办法执行以下操作

I get an error related to Ipython. Is there a way to do the following

if run_from_ipython():
    from IPython.Debugger import Tracer
    debug = Tracer()

这样我只在需要时导入Tracer（）函数。

This way I only import the Tracer() function when I need it.

推荐答案

这可能就是你要找的东西：

This is probably the kind of thing you are looking for:

def run_from_ipython():
    try:
        __IPYTHON__
        return True
    except NameError:
        return False
