Practical Data Wrangling

Matching the end of a string

Similarly, if the $ symbol is used at the end of the pattern string, the regular expression will only produce a match if the pattern appears at the end of the search string:

....a_at_end = re.compile("a$")if a_at_end.search("a"):    print("'a' is a match")if a_at_end.search("a 1234"):    print("'a 1234' is a match")if a_at_end.search("1234 a"):    print("'1234 a' is a match")
