1 . The function takes multiple iterable objects as input and returns an iterator that produces tuples, each containing the next value from each input iterable. If an iterable is exhausted first, the value at that position is filled with the specified `fillvalue`.

2 . This function takes a list as input and then uses the sample method from the random module to shuffle the order of the elements in the list and return it.

3 . This function merges two lists and sorts them using the sorted function

4 . This function calculates the square root of the input number.

5 . This function takes a string argument and returns a dictionary containing the count of each English letter (case insensitive) in the string.

6 . This function takes a list of strings as input and returns all unique palindromes in the list.

7 . This function uses the BeautifulSoup library to extract all links from the given HTML content. It can specify the tag to search for and the attributes to filter the links.

8 . This function combines multiple iterable objects into a tuple. If one of the iterable objects is longer than the others, it fills the remaining positions with `fillvalue`.

9 . The function is used to merge multiple iterable objects into one iterator. If the iterables are of uneven length, the specified value is used to fill in the shorter iterables.

10 . This function first generates a random string of a specified length, then retrieves the current time and current directory, converts the string to JSON format, calculates its MD5 hash, checks if it contains a digit, and finally calculates the length of the string and prints all results.
