In this article, we will show you how to transpose a matrix in a single line in python. Below are the various ways to accomplish this task − Using Nested List Comprehension Using NumPy Module Using zip() Function What is the transpose of the matrix? A matrix transpose is the interchanging of rows and columns. It is abbreviated to A'. The element in the ith row and jth column of A' will be moved to the jth row and ith column of A' Using Nested List Comprehension Algorithm (Steps) Following are the Algorithm/steps to be followed to ...

In this article, we will show you how to randomly select an item from a string using python. Below are the various methods in python to accomplish this task − Using random.choice() method Using random.randrange() method Using random.randint() method Using random.random() Using random.sample() method Using random.choices() method Assume we have taken a string containing some elements. We will generate a random element from the given input string using different methods as specified above. Method 1: Using random.choice() method Algorithm (Steps) Following are the Algorithm/steps to be followed to perform the desired task − Use the import keyword ... Read More
In this article, we will show you how to pick a random number not in a list in python. Below are the various methods to accomplish this task − Using random.choice() function Using random.choice() function and List Comprehension Using random.choice() & set() functions Using random.randrange() function Using random.choice() function The random.choice() method returns a random element from the specified sequence. The sequence could be a string, a range, a list, a tuple, or anything else. Syntax random.choice(sequence) Parameters sequence − any sequence like list, tuple etc. Algorithm (Steps) Following are the Algorithm/steps to be followed to perform ... Read More
In this article, we will show you how to convert decimal to binary using recursion in python. A decimal number is the most familiar number system to the general public. It is base 10 which has only 10 symbols − 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Whereas Binary number is the most familiar number system to digital systems, networking, and computer professionals. It is base 2 which has only 2 symbols: 0 and 1, these digits can be represented by off and on respectively. When we convert a number from the decimal number system to ... Read More
In this article, we will show you how to check if a number is odd or even in python. Below are the methods to accomplish this task − Using modulo (%) operator Using Recursion Using the Binary AND (&) operator Using modulo (%) operator Python's modulo (%) operator (also called the remainder operator) is useful to determine if a number is odd or even. We obtain the remainder of the division of a number by 2. If it is 0, it is even otherwise it is odd Even Number − A number that can be divided by 2, ... Read More
In this article, we will show you how to calculate the square root of a number in Python. Below are the various methods to accomplish this task − Calculating square root using sqrt() Calculating the square root using the pow() function Calculating the square root using the exponent operator Calculating square root using the cmath module What is the square root of a number? The square root of a number is a value when multiplied by itself returns that same number. Example − 5 x 5 = 25, hence the square root of 25 is 5. However -5 ... Read More
In this article, we will show you how to find the largest integer less than x in python. The Greatest Integer Function [X] denotes an integral part of the real number x that is the closest and smallest integer to x. It's also called the X-floor. [x]=the largest integer less than or equal to x. Generally If n
In this tutorial, we are going to learn how to get the image element on which the current instance is based on using FabricJS. We can create an Image object by creating an instance of fabric.Image. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. In order to get the image element on which the current instance is based on, we use the getElement method. Syntax getElement(): HTMLImageElement Using the getElement method Example In this example, we have used the getElement method to obtain ... Read More
In this tutorial, we are going to learn how to set a multiplier to scale the cloned image using FabricJS. We can create an Image object by creating an instance of fabric.Image. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. In order to set a multiplier to scale the cloned image, we use the multiplier property. Syntax cloneAsImage( callback: function, { multiplier: Number}: Object): fabric.Object Parameters callback (optional) − This parameter is a function which is to be invoked with ... Read More
In this tutorial, we are going to learn how to scale an Image object to a given width using FabricJS. We can create an Image object by creating an instance of fabric.Image. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. In order to scale an Image object to a given width, we use the scaleToWidth method. Syntax scaleToWidth(value: Number, absolute: Boolean): fabric.Object Parameters value − This parameter accepts a Number which determines the new width value of our Image object. absolute ... Read More
