In this Python tutorial, you will learn everything about tuples in Python, including multiple ways to create a tuple and access its values with practical examples and some realistic scenarios. While working on the Python project, we needed to securely store the user’s data, such as name, age, email, etc., in a fixed order that cannot be changed. In this situation, we can store the data in a tuple in Python. What is Tuple in Python? A tuple is an ordered collection in Python that can store multiple values of the same or different datatypes. It is also known as a Homogeneous or Heterogeneous Col ..read more

In this Python tutorial, I will show you how to convert a dict to a string Python. While creating a web application using Python, I needed to send the data in a dictionary over the network, but we couldn’t send the dictionary objects over the network. So I needed a way to convert the dictionary into a format that is sendable over the network, and there was a solution that was converting the dict string into json string. I used the dumps() method from the Python JSON module and converted the dictionary objects into strings. In this tutorial, I have explained how I converted the dictionary into ..read more

In this Python tutorial, I will show you how to convert string to byte array Python. I needed to send the user a message in my chat application over the network. Since you can’t send the raw message over the network, it is good practice to convert the message into bytes and send it over the network. For that, first, I had to convert the message into a byte array and then send it over the network. I researched the internet and found three solutions to convert string to byte array. The method I used to convert string to byte was bytearray(); after converting, I sent the data over the network to ..read more

Want to handle file errors in Python? In this tutorial, you will learn how to handle errors when a file does not exist in Python. We will go through 5 methods with practical examples to handle Python file-do-not-exist exceptions. It is very important to understand which type of error you can get when working on real-time projects because it directly affects your application, such as crashing or stopping working in its flow. While working on an image background removal application in Python, I needed to handle the File does not exist error. This means that users cannot open files that have been ..read more

In this tutorial, you will learn “How to compare two lists in Python and return non-matches values” with practical examples. While working on a large amount of data, I was required to compare two columns(lists) and extract the unmatched elements from the lists. I found some different techniques for comparing two lists and returning non-matching values in Python. I thought I would share this information with you so that you can learn about all the different approaches and realistic examples in this Python tutorial. In this article, I have explained 5 different methods for finding the unmatched ..read more

In this Python tutorial, we will discuss “How to convert a dict to string in Python” with different approaches and built-in methods. Convert a Dict to String in Python When I needed to store all the JSON data (dictionary) in the text file, I was looking for a way to convert a dict to a string in Python, and I found 5 different methods and techniques that helped me out. Suppose there is a dictionary like this “state= {“California”: 39512223, “Texas”: 29145505, “Florida”: 21538187,” New York”: 19453561}” and if we convert this into a string, still it looks the same as a dictionary, but when you ..read more

In this Python tutorial, I will show you how to call by value and call by reference in Python. Both the concepts of call by value and call by reference are very helpful in memory management, data manipulation, and even API development. In this tutorial, I have explained the meaning of call by value and reference and, with examples, shown how to implement these concepts and how they differ. Let’s begin, What does Call By Value and Call By Reference in Python Mean? In several programming languages, you can pass the data to the function argument in two ways: by value and reference (address). Cal ..read more

In this Python tutorial, I will show you how to download Python and install it on your systems, whether you are a Windows, Linux, or macOS user. First, I will show you how to install Python on Windows 11, then on Linux distros called Ubuntu, and finally, you will see how to install it on MacOS (version Sonoma). As a Python developer, you must know how to install Python on different operating systems. There are several reasons, one of which I will explain here, for cross-platform development. Python can be run on other platforms so that you can write and test a program on your different platfor ..read more

In this Python tutorial, we will discuss “How to use the If Else statement in Python” with some practical examples. In Python, an if-else statement is also known as a conditional statement, which is used to control the program’s execution flow based on a given condition. In real life, we always make decisions based on conditions or situations. For example, if it’s raining outside, then I will take an umbrella; otherwise, “I will not.” So we decided based on the conditions. In programming language, we make programs to decide which block of code should be executed. Conditional statements are a f ..read more

In this TensorFlow tutorial, I will show you how to fix the error Attributeerror: module ‘tensorflow.keras.layers’ has no attribute ‘multiheadattention’. In this tutorial, I have explained the solution to this error; the solution is based on the version of TensorFlow. Additionally, I have explained what you can do to avoid this error in the near future. Attributeerror: module ‘tensorflow.keras.layers’ has no attribute ‘multiheadattention’ The error Attributeerror: module ‘tensorflow.keras.layers’ has no attribute ‘multiheadattention’ means, the module ‘tensorflow.keras.layers’ doesn’t contain ..read more
