Python program to split the even and odd elements into two different lists.
In this article, we are going to learn about splitting the even and odd elements into two different lists. This involves looping each element in a list and checking whether it is divisible by 2. Even numbers are those that gives the remainder '0' when divided by 2, while the odd numbers leaves a remainder '1'. Using Python append() Method The Python append() method is used to add the new object to a list. It accepts an object as a argument and inserts it at the end of the existing list. Syntax Following is the syntax of Python ...
Read MoreSequenceMatcher in Python for Longest Common Substring.
The SequenceMatcher class is the part of the Python difflib module. It is used to compare sequence (such as lists or strings) and finds the similarities between them. The task is to find the Longest Common Substring, i.e, the longest sequence of the characters that appears contiguously in both strings. which is different from the Longest Common Subsequence, where the characters may appear in the same order but not repeatedly. Using find_longest_match() Method The find_longest_match() method is used to find the longest matching sequence of elements between two sequences. It is the part of the Python difflib module. ...
Read MorePython program to find Maximum and minimum element’s position in a list?
In Python, Lists are one of the data types. It is sequence of comma separated items, enclosed in the square brackets []. They are widely used to store collection of item. In this article, we are going to learn about finding the maximum and minimum element's position in a list. This can be achieved by using the Python built-in functions like max(), min() and index(). Using Python max() Function The Python max() function is used to return the maximum element in the list. If the list contains the numbers, comparison is done numerically, but if the list contains strings, ...
Read MorePython program to check if binary representation of two numbers are anagram.
The binary numbers are the basis of how data is stored, processed and transferred. Every integer is internally represented by using a sequence of bits (combination of 0s and 1s). In this article, we will learn how to check if binary representation of two numbers are anagram. Two numbers are said to be binary anagrams if their binary representations contains the same number of 1s and 0s. For example, the number 12 in binary is 1100 and the number 10 in binary is 1010, both have two 0s and two 1s, making them binary anagrams. Using collections.Counter() Class ...
Read MorePython program to find missing and additional values in two lists?
In this article, we will explore how to find missing and additional values in two lists. This type of comparison is can be encountered in the real-world scenarios such as data validation or system synchronization. The task is to determine which elements are missing in one list and what unexpected elements were received. This can be achieved by using the python built-in data structures like sets that allows for easy comparison. Using set() Function The python set() function is used to used to create a new set. A set is a collection of unique elements (each ...
Read MorePython program to list the difference between two lists.
In Python, Lists are one of the built-in data type used for storing collections of data. Python list is a sequence of comma separated items, enclosed in square brackets[]. They are flexible, easy to manipulate and widely used in various applications. In this article, we will explore to list the difference between two lists. Python provides the several built-in methods for achieving this. Using set.difference() Method The python set.difference() method is used to return the new set containing the elements that are present in the first set but not in any other sets provided as arguments. ...
Read MorePython program to communicate between parent and child process using the pipe.
Inter-process communication (IPC) is essential, When multiple processes need to share the data and work together. In Python, multiprocessing module provides various IPC mechanisms, Out of which one is the pipe. The pipe allows the data to be transferred from one process to another in a two-way (duplex) or one-way mode. It is useful when a parent process creates a child process and want them to exchange messages or data. Python multiprocessing.Pipe() Method The multiprocessing.Pipe() is a method in the Python multiprocessing module that return the pair of connection objects connected by a pipe. This pipe can be ...
Read MoreClass or Static Variables in Python?
In this article we are going to learn about class or static variables on python. The class variables or static variables that are used to share across all the instances of a class. Unlike the instance variables which are specific to each object, Class variables maintain the common value for all the objects of the class. They are defined within the class but outside any instance methods, making them accessible to all the instances. These variables are used when we want to have a single shared state or value among all instance. Example 1 Let's look ...
Read MoreHow to import a single function from a Python module?
In Python, the module is a file containing Python definitions and statements. For keeping the code organized, we often write functions in separate modules and import them into main program. While importing the entire module, sometimes we only need a single function from it. Python provides a direct way to do this using the from module_name import function_name syntax. Importing sqrt() from math module In this approach, we are going to use from math module importing the sqrt to import only the sqrt function. The Python sqrt() function is used to calculate the square root of ...
Read MoreHow can I get a list of locally installed Python modules?
Python is a flexible programming language that consists of thousands of libraries and libraries. As the Python environment grows with the installations, it is important to be able to check which packages are currently installed. Whether you are debugging or documenting the environment, listing locally installed python modules can be useful. In this article, we will explore the different ways to get a list of locally installed python modules using the built-in tools and external commands. Using pip list The pip is the Python package installer and the list is tje subcommand that shows all the installed ...
