In this method, we useset()andlen()function to calculate the number of unique items present in the list. Set is another data type available in Python just like lists. Set is different from a list because set is an unordered data type while the list is an ordered data type and most im...
The np.count() function in Python is a tool used for counting occurrences of a specific substring within each element of an array. Part of the NumPy library, this function works efficiently on arrays, including multi-dimensional ones, to find and count instances of a given word or character....
In this tutorial, we'll learn how to count the number of times a word occurred in a list in Python using Pandas/Numpy, the count() function, a for loop, and the Counter() function of the collections module and benchmark them.
