Given a Snippet, the combined code from all the Python snippets among its children can be retrieved via:
pythonCode(Snippet) : String
pythonCode(snippet(uid:String)) ⇒ Pharo:"signature stringTerm: (LzPythonCode fromChildrenOfSnippet: uid value)"
Some Python code, retrievable as pythonCode(firstSnippetStartingWith("Some Python code", "Python code")) ⇒ "import sys
print(sys.version)
"
import sys
print(sys.version)
