NumPy

This function generates a random matrix of shape (arg1, arg2) with elements from a specified distribution. It first randomly selects a distribution type, then selects a random parameter for the chosen distribution, and finally generates the matrix based on the parameter.

aiohttp, asyncio

The function above creates an asynchronous HTTP client using the aiohttp library, fetches random user information from the public API at https://randomuser.me/, and prints it out.

Graylog API client

This function uses the Graylog API client to query the stream ID for a given stream name. It accepts the stream name, query, and an instance of the Graylog API client as parameters, and returns the found stream ID or None. If the query does not return any results, None is returned.

PyBluez, Bluetooth, discover_devices

This function uses the Bluetooth class from the PyBluez library and the discover_devices method to scan for available Bluetooth devices. It sets a scan duration of 5 seconds, looks for devices with a specific service class, and attempts to find the device name.

PySerial

This function randomly selects a serial port name and connects to that port with a specified baudrate. The function first checks the type of the port name and baudrate, then randomly selects a port from a predefined list of common ports, creates a serial connection, and returns the connection object.

PyBluez, BluetoothSocket, RFCOMM, discover_devices

This function uses the bluetooth module from the PyBluez library to scan for Bluetooth devices within range and returns a list of devices with their names.

The code uses the OpenCV and NumPy libraries. OpenCV is used for image processing tasks such as color conversion, mask creation, and contour detection. NumPy is used for numerical operations.

This code defines a function that detects and displays the red regions in an image. It first converts the image from BGR color space to HSV color space, then defines the HSV range for red color and finds these colors through mask operations. Finally, it finds and draws the contours of these red regions.

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.
