Another approach is to create an array using thearray()function after importing the numpy module. Further, we will use theunique()function to remove the duplicate elements from the list. Finally, we will calculate the length of that array to get the count of the unique elements. Solution: #...
Statistical functions are used in many popular applications such as Microsoft Excel. Pandas are used to represent and manipulate data in the form of tables too, so learning how to use these functions is a must. Since Python Pandas does not have an explicit COUNTIF() function, we will explore...

To count how many values per key in a Python dictionary object, you need to use aforloop and theitems()method to iterate over the dictionary object. In each iteration, you can count the values using thelen()function. For example, suppose you have a dictionary object with list values as ...
The pathlib.Path.iterdir() of the pathlib module is used to get the path objects of the contents of a directory in Python; this is executed whenever the directory’s path is known.from pathlib import Path def count_files_in_directory(directory_path): path = Path(directory_path) file_...
