How to split string by character length and not include next section of string?

If I’m splitting a string by character length and wanted the split string to not include the next section of the string which is specified by a comma or by another wildcard. How do I do this whilst being below the character limit?

raw_string = ('ABCD,DEFG,HIJK)
split_string = re.findall(.{1,10}, raw_string)
> split_string = 'ABCD,DEFG,H'

How do I set my Regex so that my string produces something like this?

>split_string = "ABCD,DEFG"

    You might let it backtrack until it can assert a comma to the right.

    Note that you are using re.findall that will return a list of matches.

    import re

raw_string = 'ABCD,DEFG,HIJK'
split_string = re.findall(r".{1,10}(?=,)", raw_string)
print(split_string)

    Output

    ['ABCD,DEFG']
