[docs] [issue16020] Missing >>> in Python code example

[Chris Jerdonek]

Chris Jerdonek added the comment:

Thanks for the report.  Minor clarification for future reference.  Subsequent lines should begin with "..." (when doctest-style is used):

>>> def breadth_first_search(unsearched):
...     node = unsearched.popleft()
etc.
