This regular expression splits a string "op" into two groups based on the pattern "(\d.*)":
1. The first group includes any digits that appear at the beginning of the string. This group is enclosed in parentheses and is represented by the pattern "\d.*". The "\d" matches any digit character, while the ".*" matches any number of characters after the digit.
2. The second group includes the rest of the string after the digits, if any. This group is represented by the pattern ".*" which matches any number of characters.
The "r" before the regular expression indicates that it is a raw string, which means that any backslashes are treated as literal characters rather than escape characters.
The "re.split()" function then uses this regular expression to split the input string "op" into a list of strings. The regular expression pattern is used as the delimiter to split the string. The resulting list will contain the two groups that match the pattern, along with any non-matching text.
