In this tutorial we will discuss about difference between np.asarray() and np.array(). The main difference between both are Numpy functions used to generate arrays from array like objects but they have some difference on their behaviour. The array() method creates a copy of an existing object whereas asarray creates a new object only when needed. …
The complex() function returns a complex number by specifying a real number and an imaginary number. Complex numbers in python are written using the ‘j’ suffix, which represents the imaginary part. For example, ‘3+4j’ is a complex number where 3 is a real part and 4 is the imaginary part. Syntax : complex(real, imaginary) Parameter …
Python’s numpy.isinf() is used to test if element is a positive or negative infinity or not. It returns a Boolean array with same shape as the input array, where each element is ‘True’ if the corresponding element of the input array is either positive or negative infinity, and ‘False’ otherwise. Syntax: numpy.isinf(array [,out]) Parameters: array …
Description: To count a special characters in a string in python, we can use a string method “Regular expression”. In this ‘re’ special characters can be defined all the non-alphanumeric characters in the string. Using Regular Expression:import redef count_special_characters(s): special_characters_pattern = r'[^a-zA-Z0-9\s]’ special_characters = re.findall(special_character_pattern, s) return len(special_characters)input_string = “Hi, hello, Welcome! to @1year”count = …
Hello! We’re going to explore how to optimize a modeling pipeline using scikit-learn, one of the most popular machine-learning libraries in Python. Optimizing your pipeline can greatly enhance the performance of your models by automating the process of selecting the best parameters and improving the overall workflow. We will be using the famous Iris dataset, …

Hey there! Ready to dive into the exciting world of time series analysis? In this tutorial, we will learn how to use TensorFlow, Google’s open-source library for machine learning, to analyze and predict time series data. We will work with a dataset of daily minimum temperatures in Melbourne and walk through each step. By the …
In this tutorial you will learn about the Bitwise operators in Python. In python bitwise operators are used to perform bitwise calculations on integers. These integers are first converted into binary and then operations are performed on each bit. Python provides several bitwise operators each serving a unique purpose. These operators include AND OR NOT …
In this tutorial, we will learn about numpy.ndarray.view() in python with some practical examples. In Python, lists can be used similarly to arrays, but their processing speed is relatively slow. NumPy aims to offer an array object that is up to 50 times faster than traditional python lists. Unlike lists, NumPy arrays are stored in …
To change the playback speed of an MP3 file in Python, utilizing libraries such as pydub for audio manipulation and pydub.playback for playback is essential for a seamless process. This task can be achieved efficiently by following a step-by-step guide. Firstly, import the necessary libraries and install them using pip. Next, load the MP3 file …
In this content, we will learn the converting of audio to video using static images in python. Introduction We are going to convert an audio file to video file using images provided by the user to be shown during the duration of the video using python. To do this, we will first convert the images …
