The difference of two lists have been discussed many times, but sometimes we have a large number of data and we need to find the difference i.e the elements in dict2 not in 1 to reduce the redundancies. Let’s discuss certain ways in which this can be done....

Given a dictionary with list as values, check if all lists are empty....

Given a string, write a Python program to find whether a string contains only letters and no other keywords. Let’s discuss a few methods to complete the task....

In Python, we can bind structural information in form of tuples and then can retrieve the same. But sometimes we require the information of tuple corresponding to maximum value of other tuple indexes. This functionality has many applications such as ranking. Let’s discuss certain ways in which this can be achieved....

OpenCV is the huge open-source library for computer vision, machine learning, and image processing and now it plays a major role in real-time operation which is very important in today’s systems. By using it, one can process images and videos to identify objects, faces, or even the handwriting of a human. When it integrated with various libraries, such as Numpy, Python is capable of processing the OpenCV array structure for analysis. Note: For more information, refer to OpenCV Python Tutorial...

Sometimes, while working with data, we can have problem in which we need to perform the extraction of only unique values from dictionary values list. This can have application in many domains such as web development. Lets discuss certain ways in which this task can be performed....

Sometimes, while working with data, we need to perform the string tokenization of the strings that we might get as an input as list of strings. This has a usecase in many application of Machine Learning. Let’s discuss certain ways in which this can be done....

You have given a list of dictionaries, the task is to return a single dictionary with sum values with the same key. Let’s discuss different methods to do the task....

Dictionary is a collection which is unordered, changeable and indexed. In Python, dictionaries are written with curly brackets, and they have keys and values. It is widely used in day to day programming, web development, and machine learning. Combining dictionaries is very common task in operations of dictionary. Let’s see how to combine the values of two dictionaries having same key....

Given a text file fname, the task is to count the total number of characters, words, spaces, and lines in the file....

Sometimes while working in Python we can have a problem in which we need to restrict the data elements to just one type. A list can be heterogeneous, can have data of multiple data types and it is sometimes undesirable. There is a need to convert this to a data structure that restricts the type of data....

Sometimes, more than finding a substring, we might need to get the string that is occurring after the substring has been found. Let’s discuss certain ways in which this task can be performed using Python....
