easy way to do this - 2022
<ul>
<li>figure out where you're loading ipdb from</li>
<li><code>import ipdb</code></li>
<li><code>print(ipdb.__file__)</code></li>
<li>open <code>__main__.py</code> from that folder</li>
<li>search for <code>except (configparser.NoSectionError, configparser.NoOptionError):</code></li>
<li>below it is 3. Change that to your desired value</li>
</ul>
Why this is better than the proper way:
<ul>
<li>I don't need to learn a new configuration language</li>
<li>I don't need to create a new configfile</li>
<li>I don't need to debug why my configfile isn't being picked up</li>
<li>you never get tricked by file scoping/permissions/visibility since you are sure which ipdb module is being loaded (i.e. it covers virtualenvs too)</li>
<li>I don't have to talk to upstream and try to convince them to adopt this default.</li>
</ul>

You can type <code>l</code> in ipdb to show a few more lines of the current context

and you can keep hitting <code>l</code> and it continue revealing more lines from the file

If you want to show more lines of context around the current line you can type <code>l</code> to get the current line. And then type <code>l curr_line - 10, curr_line + 10</code>. Say I was on line 50 and I wanted to see the surrounding 20 lines. I would type: <code>l 40,60</code> to see more.

As noted by @jrieke in a comment, you can also hit <code>ll</code> to get a bigger chunk of context. One nice thing about <code>ll</code> is it will print all the way back from the start of the current method (whereas consecutive <code>l</code>s reveal further lines below your breakpoint).

You can get more context by doing:

</code></pre>
<h1>Permanent context size</h1>
To permanently set context size, find the installation directory by doing
<pre><code>python -c 'import ipdb; print(ipdb)'
</code></pre>
which will show you a <code>__init__.py</code> file. Open that file and find the line (which may also be found in IPDB's <code>__main__.py</code>:
<pre><code>def set_trace(frame=None, context=3):
</code></pre>
change the <code>3</code> to however many context lines you want.

Edit: it was implemented: <a href="https://stackoverflow.com/a/66474153/895245">https://stackoverflow.com/a/66474153/895245</a>
As a quick complement to <a href="https://stackoverflow.com/a/35883288/895245">this other answer</a> this is the one liner that you generally want to add to the code you want to debug:
<pre><code>__import__('ipdb').set_trace(context=21)
</code></pre>
You likely want to add a shortcut for that from your editor, e.g. for <a href="https://github.com/garbas/vim-snipmate" rel="nofollow noreferrer">Vim snipmat</a> I have:
<pre><code>snippet ipd
 __import__('ipdb').set_trace(context=21)
</code></pre>
so I can type just <code>ipd&lt;tab&gt;</code> and it expands to the breakpoint. Then removing it is easy with <code>dd</code> since everything is contained in a single line.

If you want to stop execution in a running system, as others said, use:

<pre class="lang-py prettyprint-override"><code>ipdb.set_trace(context=number_of_lines)

For running some function or an object's method modifying this context lines is a little bit tricky. The only way I found was:

<pre class="lang-py prettyprint-override"><code>ipdb.__main__._init_pdb(context=number_of_lines).runcall(callable, *args, **kwargs)
</code></pre>

In case it serves someone.

Here's a patch to permanently set context for your program:

(works across set_trace and post_mortem)

<pre class="lang-py prettyprint-override"><code>def ipdb_patch(context = 11):
 import ipdb
 ipdbmain = ipdb.__main__
 def _init_pdb(context=context, commands=[]):
 try : p = ipdbmain.debugger_cls(context=context)
 except TypeError : p = ipdbmain.debugger_cls()
 p.rcLines.extend(commands)
 return p
 def set_trace(frame=None, context=context):
 ipdbmain.wrap_sys_excepthook()
 if frame is None : frame = ipdbmain.sys._getframe().f_back
 p = ipdbmain._init_pdb(context).set_trace(frame)
 if p and hasattr(p, 'shell') : p.shell.restore_sys_module_state()
 ipdbmain._init_pdb = _init_pdb
 ipdb.set_trace = set_trace
 return ipdb
ipdb = ipdb_patch()
</code></pre>

to add breakpoint() functionality simply add:

<pre class="lang-py prettyprint-override"><code>import sys
sys.breakpointhook = ipdb.set_trace
</code></pre>

With that all the following commands have the right context size:

<pre class="lang-py prettyprint-override"><code>ipdb.set_trace()
breakpoint()
ipdb.post_mortem()
ipdb.pm()
%debug
</code></pre>

It does not however work with this:

<pre class="lang-py prettyprint-override"><code>In [1]: %run -d file.py
</code></pre>

If you know how to adjust that, please feel free to drop in comments

There are several ways to configure it without changing any code.
If you want to have a persistent setting in your shell, you can use <code>IPDB_CONTEXT_SIZE</code> variable. Add the following to your <code>.bashrc</code>/<code>.zshrc</code>/etc.:
<pre><code>export IPDB_CONTEXT_SIZE=10
</code></pre>
Thanks to <a href="https://stackoverflow.com/users/11715259">N1ngu</a> for pointing this out.
Keep in mind though, that this is implemented in <code>ipdb</code> itself, not in <code>IPython</code>, so while it will work when used with <code>ipdb.set_trace()</code>, it doesn't apply to the <code>%debug</code> magic.
Starting with IPython 7.21 you can also use <code>context</code> command in ipdb to change the number of backtrace lines shown:
<pre class="lang-py prettyprint-override"><code>import ipdb; ipdb.set_trace()
...
ipdb&gt; context 10
ipdb&gt; bt
</code></pre>
<a href="https://i.stack.imgur.com/ZQydf.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ZQydf.png" alt="Screenshot of IPDB after the context command has been used" /></a>
You can put the following line in <code>~/.ipdb</code> to make ipdb set it automatically:
<pre><code>context = 10
</code></pre>
Apart from that, there's also the old <code>context=</code> argument in <code>set_trace()</code>, which makes it possible to set it at the time of running the debugger:
<pre class="lang-py prettyprint-override"><code>import ipdb; ipdb.set_trace(context=10)
# or, if you've set PYTHONBREAKPOINT=ipdb.set_trace in your environment
breakpoint(context=10)
</code></pre>

blocks|key|3017076|text|按照@erock618+618的方式，在最近的ipdb版本中，您可以使用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3017077|debugger_cls+=+ipdb.__main__._get_debugger_cls()|code-block|syntax|javascript|3017078|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Following the @erock618 way, in more recent ipdb versions you can use:

</code></pre>

By default, during debugging in IPython, <a href="http://pypi.python.org/pypi/ipdb" rel="noreferrer">ipdb</a> shows one line above and one line below the current position in code. 

Is there an easy way to make the area shown a bit bigger? I'd think it would be configurable, but haven't been able to find it.

How can I make ipdb show more lines of context while debugging?
