<p>扩展Sven Marnach的答案,下面是一个<a href="http://pyparsing.wikispaces.com/" rel="nofollow">pyparsing</a>语法的示例,它应该适合您:</p>
<pre><code>from pyparsing import (ZeroOrMore, Word, printables, Forward,
Group, Suppress, Dict)
collection = Forward()
simple_value = Word(printables, excludeChars='()=;')
key = simple_value
inner_collection = Suppress('(') + collection + Suppress(')')
value = simple_value ^ inner_collection
key_and_value = Group(key + Suppress('=') + value)
collection << Dict(key_and_value + ZeroOrMore(Suppress(';') + key_and_value))
coll = collection.parseString(
"key1=value1;key2=value2;key3=(key3.1=value3.1;key3.2=value3.2)")
print coll['key1'] # value1
print coll['key2'] # value2
print coll['key3']['key3.1'] # value3.1
</code></pre>
