Introduction In machine learning, classification problems are one of the most widely seen problems, where machine learning models are built to classify several categories of the target variables. However, the classification report and confusion matrics are used in order to evaluate the performance of the model and to check where the model is making mistakes. In this article, we will discuss the classification report and confusion matrics, what they are, how we can use them, and what their interpretation is by calculating the same code examples in Python. This article will help one to clear an idea about ... Read More

The reverse slice is defined by creating a slice that begins with the length of the string and ends with the 0th index. For reversing the list element it will use the negative value notation, where we can get a reversed order of the original list element. In Python, we have some built-in functions such as append(), len(), and, range() will be used to solve the K elements Reversed Slice. Syntax The following syntax is used in the examples- append() This built-in method in Python can be used to add the element at the end of the list. len() ... Read More

The pygame is the name of the module of Python that helps to build the code for graphics such as rectangles, squares, circles, etc. It is also used the write the code for animation programs in Python. Eclipse is famous for Java IDE but here we have to set the environment of Python to run the program based on Pygame. System requirement Memory: 4 GB CPU: Intel Core i5 Storage: 30GB prefer to be good Operating System: windows 7/10/11 Steps to set up pygame with Eclipse The following syntax is used in the examples- Step 1: Start searching ...

The indexing is the specific position of the element from the list. The unequal elements of two lists refer to those indexes whose elements are not matched from both lists. In Python, we have some built-in functions like enumerate(), zip(), filter(), etc. that can be used to filter unequal elements of two lists corresponding same index. Let’s take an example of this Given list, lst_1 = [10, 20, 30, 40, 50] lst_2 = [1, 20, 3, 40, 50] Then the final result becomes [20, 40, 50] these elements from the list matches the corresponding same index. Syntax The following syntax ... Read More

Python refers to the high-level programming language that has various tools and built-in functions to analyze text data. This problem statement is a common task that uses some built-in functions- filter(), isdigit(), isalpha(), findall(), split(), and, append() to find the both alphabet and numbers using Python. Let’s see how to take the input of the program to get the result: Input my_text = "WELCOME TO CLUB100" Output CLUB100 Syntax The following syntax is used in the examples- filter() The filter() method is applied when it filter the items based on specific conditions. In simple terms, it allows ... Read More

The tuple list defines the two different datatypes of Python that represent the static and dynamic characteristics respectively. In a dictionary, we can create keys using tuples whereas lists cannot be used as keys. In Python, we have some built-in functions like next(), items(), index(), lambda, and, min() will be used to Find the first element by the second in the tuple list. This type of circumstance occurs when the second element holds the important information as a key for identifying the desired tuple. Let’s take an example of this: The given tuple list, my_tup = [("India", 35), ("Indonesia", 12), ... Read More

The dictionary is one of the most popular among four datatypes known for unordered collection of key-value pairs. The Python matrix will be used to represent the list of lists whereas an inner list represents the row-value of a matrix. A coordinate dictionary is defined as tuples to set the rows and columns by giving coordinates value. In Python, we have some built-in functions such as len(), range(), zip(), etc. that can be used to solve Convert Matrix to Coordinate dictionary. Syntax The following syntax is used in the examples- len() The len() is a built-in method in Python ... Read More

The indices are the position of the elements present in the list whereas K defines the specific value to target the smallest element from the list. Sometimes, we are working in the field of web development and database these tasks generally occur to solve this problem statement. In Python, we have built-in functions like sorted(), range(), len(), etc. that will be used to find the indices for k Smallest elements. Syntax The following syntax is used in the examples- sorted() The sorted() is an in-built function in Python that helps to return the new sorted list while ... Read More

The position of the smallest value within a list is indicated by the index of the minimum element. Each list element has a distinct index that increases by one with each additional element after the first, starting at zero for the first element. By determining the index of the minimum element, we can locate the exact position of the smallest value within the list. In Python, we have some built-in functions like min(), index(), argmin(), lambda(), and, enumerate() to find the index of the minimum element in the list. Syntax The following syntax is used in the examples- min() ... Read More

Lists are a powerful data structure in Python that can hold many values of various types. We may come across nested lists where the items themselves are lists. In such circumstances, flattening the list and retrieving individual elements from the hierarchical structure may be essential. In Python, we have some built-in functions- chain(), extend(), and append() that can be used to solve the Flatten List to individual elements. Let’s take an example of this: Input # Flatten List my_list = [[11, 21, 31], [20, 30, 40], [4, 5, 6], [1, 2, 3]] Output # individual element in the list ... Read More
