Ipdb and method documentation

问题:

I have to analyze methods a foreign API, and how I usually do it it to write a test script, or find an example code, do a

ipdb.set_trace()

Where I want to experiment, and than take a look at currently available variables, objects and their methods. However, when I want to check the documentation the way Ipython offers

object.method?

I get

*** SyntaxError: invalid syntax (<stdin>, line 1)

---

If I try

help(object.method)

It gives

*** No help on (object.method)

---

Does that mean that there is no documentation for the selected method, or am I using the wrong way of calling it?

回答1:

The help() function is actually a wrapper around pydoc.help() which means that you can do something like:

ipdb> import math
ipdb> import pydoc
ipdb> pydoc.help(math.log)

回答2:

Actually !help(object.method) works, you just need to signify with ! that it's a python command, not ipdb help command. Though convenient question mark doesn't work that way unfortunately.
