Algorithm for extracting comments from Python source code

[Gribouillis]

Oficially, only the # ... comments exist in Python, but you can't prevent people from overusing the syntax by cluttering the code with strings. This could be done in many strange ways, for example

((
'''Here is a new strange
comment included in parenthesis'''),

"""It really does nothing useful, so
it's probably a comment, but it is impossible to guess"""
)

Also note that there are other paired delimiters in Python, namely { } and [ ]
