![]() 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.
