![]() This error is quite common in Python 3 programs, especially for beginners who are not familiar with the differences between Python 2 and Python 3. This could lead to unexpected behavior or errors in program, which could be difficult to diagnose and fix. If working on a Python project, that requires the Queue module and there is a “No module named Queue” error, it is important to rectify the error because the Queue module provides functionality for implementing queue data structures in Python.Īdditionally, if the code depends on the Queue module and the error is not rectified, code will not run correctly. Need to rectify the error ‘No module named Queue’ In this case, installation needs to be checked, or it is required to try running the code in a different environment to see if the issue persists. If the user is still receiving the error after using queue instead of Queue, it could be due to a problem with the Python installation or environment. In order to fix the error, we should import the queue module instead, like this: Below is an example to produce the error: Therefore, if one is using Python 3.x and tries to import Queue, he will receive a “No module named Queue” error. ![]() However, if one gets the error message “No module named Queue”, it’s possible that the code is being run using Python 3.x, where the module has been renamed to queue (lowercase “q”). The Queue module in Python is part of the standard library and should be available without the need for any additional installation. However, other queue implementations can also be used that is provided by the queue module, such as PriorityQueue (for a priority queue) and LifoQueue (for a Last-In, First-Out queue). Finally, we check if the queue is empty using empty() method.īy default, the Queue class implements a thread-safe, synchronized FIFO queue. In the below example, we are creating a queue using Python 3 and trying to add elements using put () method and retrieve them in the order they were added using the get() method. Let us take an example to create a simple FIFO (First-In, First-Out) queue. We can create a queue by using the queue module, which provides a variety of queue implementations. Renaming an object or module during the import.Importing the specific object from a module.There are several ways to import a file in Python: In Python 3, the queue module also provides several other classes for implementing different kinds of queues. Queues are a fundamental data structure in computer science and are used in many applications, such as multi-threading, task scheduling, and network programming. There are various built-in modules and also a user can create their own modules. ![]() Hence to use a module in Python, it first needs to be imported. While a module can define functions, classes, variables, and other objects, it can also contain executable code that is run when the module is imported. ![]() However, it is no longer used in Python 3 and has been replaced with the queue module, which is only around 13 years old. Hence, technically speaking, the Queue module is over 20 years old, since it has been available since Python 2 was released. However, it was renamed to queue in Python 3, which was first released in 2008. 5 Need to rectify the error ‘No module named Queue’Īdding a little context to the subject, the Queue module is a built-in module in Python 2, which was released in 2000. ![]()
