pdb: How to use the 'break' parameter?

[Kevin M. Wilson]

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

You misunderstood the notation. The | means "or", it is not something
you have to type literally.

So the syntax is:
either a line number (maybe in a different file) or a function name
optionally followed by a condition after a comma

So in your case probably something like:

break Old_MacDonald:23, name[indx] == 'd'

(I'm not sure what "indx = 4" was supposed to do. You can't assign
inside of a condition.)
