It is also important to note that by using “ re.I“, I specified that casing would be ignored.In the end it checks that a dot is found followed by one of the following extensions which must appear at the end of the string:.First makes sure that the string starts off with one more characters which are none of the following: / \ ? % * : | ”.The regular expression created does the following: IsImage = reImg.match(fileName) is not None # Determine if the file name is an image name # Defining the compiled regular expression. Let’s use Python now to check to see if a file name looks like a valid image name: Finally, you will notice that I am again using the “ i” flag to indicate that this is a case-insensitive pattern.After that, I am specifying that my parenthesized group pattern may appear once or two times in a row and that no other characters should follow. ![]() ![]()
