"# Python Code Text Splitter\n",

"PythonCodeTextSplitter splits text along python class and method definitions. It's implemented as a simple subclass of RecursiveCharacterSplitter with Python-specific separators. See the source code to see the Python syntax expected by default.\n",
"\n",
"1. How the text is split: by list of python specific characters\n",
"2. How the chunk size is measured: by length function passed in (defaults to number of characters)"
