itertools, zip_longest, islice

This function uses the `zip_longest` and `islice` functions from the `itertools` library. It combines multiple iterable objects and fills the shorter ones with a `fillvalue` if necessary.

itertools, collections.deque, collections.Counter

This function implements the functionality of the zip_longest function in the itertools library. If the input lists have different lengths, it uses fillvalue to fill the shorter lists until all lists have the same length.

List (list), Tuple (tuple), Dictionary comprehension, Lambda expression

This function takes a list of tuples and a key function (the second element of the tuple) and returns a new list of tuples sorted based on the second element.

Built-in function

Returns the absolute value of a given number. If the number is negative, it returns its opposite; otherwise, it returns the number itself.

os, re, json, time, html, base64, random, string, math

This function accepts two arguments, the first one is the directory path, and the second one is a regular expression for file names. The function lists all the files in the directory, filters out the files that match the regular expression, and outputs the file names as a JSON format. At the same time, the function will get the current time, convert it to an HTML entity, encode it as a base64 string, generate a random string, and calculate its length.

random

Selects a random element from the given five arguments and returns it

Built-in library

Define a function that performs division, and returns an error message if the divisor is zero.

List (list), Sorting (sorted)

This function is used to sort an input list and returns the sorted list.

itertools

The zip_longest function is used to combine multiple iterable objects into a single iterator. If one of the iterable objects finishes traversing, the remaining elements are filled with fillvalue.

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.
