Originally I was trying to understand the exact structure of the list being
returned by the gedcom library. It worked as it was, but I wanted to add

I added a __repr__ method at the end of the gedcom library like so:
def __repr__(self):
""" Format this element as its original string """
result = repr(self.level())
if self.pointer() != "":
result += ' ' + self.pointer()
result += ' ' + self.tag()
Take a look at the docs for
print() https://docs.python.org/3.5/library/functions.html#print
str() https://docs.python.org/3.5/library/stdtypes.html#str
repr() https://docs.python.org/3.5/library/functions.html#repr
When you do "print(object)", python will run everything through str() and
outp
At the risk of coming across as a complete dunder-head, I think my confusion
has to do with the type of data the library returns in the list. Any kind of
text or integer list I manually create, doesn't do this.
See my questions down below at the end.
If I run the following statements on the lis

Thanks for the replies. I definitely need a better understanding of "" when using Python objects. So far no luck with web searches

Not that it matters, but the reason I got off track is there are pointers

What do you mean by “return a pointer”? Python doesn't have pointers.
In the Python language, a container type (such as ‘set’, ‘list’, ‘dict’,
etc.) cont

I've been using an old text parsing library and have been able to accomplish
most of what I wanted to do. But I don't understand the list structure it uses
well enough to build additional methods.
If I print the list, it has thousands of elements within its brackets separated
by commas as I wou
