In Golang, we can use a simple indexing method and slicing method to add items to the hash collections. A hash function is used for retrieving and storing the data. In this article are going to see two different examples where we are going to use the above-mentioned methods to add items to a hash collection in go programming language. Syntax func make ([] type, size, capacity) The make function in go language is used to create an array/map it accepts the type of variable to be created, its size and capacity as arguments. Algorithm Import the required ... Read More

IntroductionBefore Google acquired Youtube, most of it was built using PHP. However, PHP at that time had a lot of restrictions for cross-platform applications, and generated a lot of clutter.  After Google’s intervention, Youtube underwent an overhaul, with a major change in interface and security. In this article, we will go through the portions of Youtube where Python is used as the primary language. Reasons why Python is Used Reducing clutter Implementing newer features Frontend and API deployment Increased security Data visualization and analysis Easier maintenance Reason 1: Reducing ClutterAs Youtube was first established ...

The coolest Python program I have ever made is Python password hasher. Let's first understand what python password hashing is. What is Password Hashing? Python Password hashing is a form of advanced encryption which can be used to store passwords online safely. In today’s world of everything being online, user passwords are one of the most easily attacked sensitive information on the internet. The password string is converted to a string of random characters using different hashing algorithms, which have been used in my program. The user is instructed to input the password string, then select the appropriate hashing algorithm ... Read More

What is a Dictionary in Python? A dictionary is Python’s own indigenous representation of a data structure, and can be considered similar to maps in C++. It is a dynamic data structure which stores key-value pairs dynamically, and is mutable. It can be better understood as an associative array, where each element is associated with its key value. Can one key hold more than one value? Although dictionaries in Python store values as key-value pairs, it is possible to store more than one value corresponding to the same key in a dictionary. This is performed by setting containers like ... Read More

Introduction Python Integers are one of the primary data types, and are used for almost all major mathematical and logical operations. In Python, integers are zero, positive or negative whole numbers without a fractional part and having unlimited precision.They can be expressed in binary, octal and hexadecimal values. In this article, we will learn how to obtain the sign of an integer. Methods Used Using simple mathematical comparison with zero Using copysign() function of math module Using numpy.sign() function Creating a method with abs() function Method 1: Using Mathematical Comparison with Zero We ...

What is an Interpreter? The Python interpreter works as a computer converter that converts high-level language to low-level machine language, which is essential for the computer to understand the code written by a programmer. Python codes are executed by an interpreter called CPython, which is written in C language and executes instructions in a block of code one line after another. Steps used Lexing Parsing Creation of byte code Conversion to machine-executable code Returning output Let’s dive into the steps in detail. Step 1: Lexing The first step of analyzing a code block in ... Read More

Introduction Python initially started off as Python version2, which is also known as the Legacy Edition. The last edition of Python2 was Python2.7, which went out of service in 2020. Python 3.x was introduced as a replacement, with a host of improvements and bug fixes over the Python 2.x versions. The older Legacy Python was a LTS software, which means it had Long-Time Support. However, Python 3.x versions are backward incompatible releases, which makes it very essential to upgrade Python 2 codebases to Python 3, to fully enjoy the ease and support of Python 3. The biggest reasons for upgrading ... Read More
