This is just an example implementation of Jan Vlcinsky answer written in Python 3 (I don't have enough reputation to post this as a comment to Jans answer). Many thanks to Jan for the push in the right direction.

To make a full (deep) copy of <code>base_config</code> into <code>new_config</code> just do the following;

<pre><code>import io
import configparser

config_string = io.StringIO()
base_config.write(config_string)
# We must reset the buffer ready for reading.
config_string.seek(0) 
new_config = configparser.ConfigParser()
new_config.read_file(config_string)
</code></pre>

Based on @Toenex answer, modified for Python 2.7:

<pre><code>import StringIO
import ConfigParser

# Create a deep copy of the configuration object
config_string = StringIO.StringIO()
base_config.write(config_string)

# We must reset the buffer to make it ready for reading. 
config_string.seek(0) 
new_config = ConfigParser.ConfigParser()
new_config.readfp(config_string)
</code></pre>

blocks|key|4628892|text|如果您使用的是Python3+(3.2%2B)，则可以使用Mapping+Protocol+Access将源配置的部分和选项复制(实际上是深度复制)到另一个ConfigParser对象。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|4628893|您可以使用read_dict()复制配置解析器的状态。|style|CODE|4628894|这是一个演示：|4628895|import+configparser

If you are using Python 3 (3.2+) you can use the <a href="https://docs.python.org/3/library/configparser.html#mapping-protocol-access" rel="nofollow noreferrer">Mapping Protocol Access</a> to copy (actually deep copy) the sections and options of a source configuration to another <a href="https://docs.python.org/3/library/configparser.html#configparser.ConfigParser" rel="nofollow noreferrer">ConfigParser</a> object.
You can use <a href="https://docs.python.org/3/library/configparser.html#configparser.ConfigParser.read_dict" rel="nofollow noreferrer"><code>read_dict()</code></a> to copy the state of a configuration parser.
Here is a demo:
<pre class="lang-py prettyprint-override"><code>import configparser

# the configuration to deep copy:
src_cfg = configparser.ConfigParser()
src_cfg.add_section(&quot;Section A&quot;)
src_cfg[&quot;Section A&quot;][&quot;key1&quot;] = &quot;value1&quot;
src_cfg[&quot;Section A&quot;][&quot;key2&quot;] = &quot;value2&quot;

# the destination configuration
dst_cfg = configparser.ConfigParser()
dst_cfg.read_dict(src_cfg)
dst_cfg.add_section(&quot;Section B&quot;)
dst_cfg[&quot;Section B&quot;][&quot;key3&quot;] = &quot;value3&quot;
</code></pre>
To display the resulting configuration, you can try:
<pre class="lang-py prettyprint-override"><code>import io

output = io.StringIO()
dst_cfg.write(output)
print(output.getvalue())
</code></pre>
You get:
<pre><code>[Section A]
key1 = value1
key2 = value2

[Section B]
key3 = value3
</code></pre>

Just starting in on my Python learning curve, and hitting a snag in porting some code up to Python 2.7. It appears that in Python 2.7 it is no longer possible to perform a deepcopy() on instances of ConfigParser. It also appears that the Python team isn't terribly interested in restoring such a capability:

<a href="http://bugs.python.org/issue16058" rel="noreferrer">http://bugs.python.org/issue16058</a> 

Can someone propose an elegant solution for manually constructing a deepcopy/duplicate of an instance of ConfigParser?

Many thanks, -Pete

Manually building a deep copy of a ConfigParser in Python 2.7

Python

刚刚开始我的Python学习曲线，在将一些代码移植到Python2.7时遇到了一些障碍。在Python2.7中，似乎不再可能在ConfigParser实例上执行深度复制()。看起来Python团队对恢复这样的功能也不是特别感兴趣：有人能提出一个优雅的解决方案来手动构建ConfigParser实例的深度副本/副本吗？非常...
