Hi, I'm not an expert on this so this is an educated guess:
You are calling drop=True and I presume that you want to delete the rows
of your dataset that satisfy a condition.
That's a problem.
If the underlying original data is stored in a dense contiguous array,
deleting chunks of it will leav

Hi,
I’m new to Python and have a simple problem that I can’t seem to find the

I want to test the first two characters of a string to check if the are numeric

Okay, wasn't aware of this group policy; will keep it in mind.

It depends on the language I’m using, in Objective C, I’d use isNumeric, just
wanted to know what the equivalent is in Python.
If you know the answer why don’t you just tell me and if you don’t, don’t post!

Hi,
No, I’ve checked leading/trailing whitespace, it seems to be related to the
variables that are returned from eyed3 in this case, for instance, I added a
check for None:
myTitleName = myID3.tag.title
if myTitleName is None:
continue
Seems like it can return a null object (or none?).

Hi,
Found it! The files name had .mp3 at the end, the problem was being masked by
null objects (or whatever) being returned by eyed3.
Checked for null objects and then stripped off the .mp3 and its mostly working
now. I’ve got a few other eyed3 errors to do with null objects but I can sort
tho

Your problem is also a typical case for regular expressions. You can

that RE does match what you intended to do, but not exactly what you
wrote in the OP. that would be '^\d\d.' start with exactly two digits
followed by any character.

It depends on the language I’m using, in Objective C, I’d use isNumeric,

Yes, it was probably just a typeo on my part.
I’ve now fixed the majority of cases but still got two strings that look
identical but fail to match, this time (again by 10cc), “I’m Mandy Fly Me”.
I’m putting money on it being a utf8 problem but I’m stuck on how to handle it.

You've misspelled "typo"!

Try printing the asciified string:
Amazing how some people bring out the heavy artillery, first! LOL!
If the question was how to remove any initial digits and perhaps whitespace in
a string, it is fairly easy to do without any functions to test if there are
digits before the title. I mean look at initial characters and move forwa
