Code introduction
The function defines a regular expression pattern to match email addresses and then extracts all email addresses from the given text using this pattern. After that, a function named xxx is defined which accepts two parameters: one for the length of the string to be generated and another for the character set. The function first checks if the arguments are integers, then generates a random string and returns it.
