Series.str.startswith doesn’t accept regex because it is intended to behave similarly to str.startswith in vanilla Python, which does not accept regex. The alternative is to use a regex match.
Use Series.str.match instead Python string starts with regex
Simple python example code using the re.match(pattern, string) function from the re module.
import re some_str = "Hello world" if re.match(r'^Hello', some_str): print("Given String start with 'Hello'")
Obviously, in this case,
somestring.startswith('hello') is better.
See which of these methods
These are most efficient to return whether a certain string begins with another string.
string.rfind('hello') == 0
string.rpartition('hello') == ''
string.rindex('hello') == 0
