Split once, delimit many
Level: Intermediate (score: 3)
Write a function that accepts a string and splits the text on the specified separators, but only on the first occurrence of the delimiter.
For example:
>>> split_once('abc: def: ijk, lmno: pqr - stu, wxy', separators=',-:')
['abc', ' def: ijk', ' lmno: pqr ', ' stu, wxy']
The separators parameter defaults to None if not supplied, in this case you should split on whitespace.
