partition(dim, sep=' ')¶
Split the strings in the DataArray at the first occurrence of separator sep.
This method splits the string at the first occurrence of sep, and returns 3 elements containing the part before the separator, the separator itself, and the part after the separator. If the separator is not found, return 3 elements containing the string itself, followed by two empty strings.
If sep is array-like, it is broadcast against the array and applied elementwise.
