pdb: How to use the 'break' parameter?

break (Old_MacDonald:23 | name[indx] == 'd', indx = 4), based on the doc spec in python.org (https://docs.python.org/3/library/pdb.html#debugger-commands)
Cell In[1], line 20
    break (Old_MacDonald:23 | name[indx] == 'd', indx = 4)
          ^
          SyntaxError: invalid syntax
I got one blank white screen when I entered the exact first line of the python.org-->b(reak) [([filename:]lineno | function) [, condition]]

I'd be obliged for an assist... KMW
