Encountering the error attributeerror: module asyncio has no attribute run in Python? What do you think causes this problem? See through the end of this article, and you will surely fully understand what this error indicates.
We truly understand how frustrating it is to encounter such errors. That is why we are here to assist you in solving this one in this article. But before that, learn the reason behind this occurrence.
In addition, we’ll provide you with a brief explanation of Python. So without further ado, here is the cause of this problem and a brief definition of Python.
Why does this error occur?
This error occurs when we try to use the run() method from the asyncio module in Python, but we're using a 3.6 version of Python or below.
For clarification, the asyncio.run() function was added to the 3.7 version of Python. So, it will have an error when we use versions 3.6 and below since the asyncio.run() function doesn't exist there.
What is Python?
Python is one of the most popular programming languages. It is used for developing a wide range of applications. It is a high-level programming language that is usually used by developers nowadays due to its flexibility.
Returning to our issue, we must take a few actions to fix this error. So now, let’s move on to our “how to fix this error” tutorial.
How to solve “module asyncio has no attribute run” in Python
Here’s how to resolve the error message stating attributeerror: module asyncio has no attribute run
in Python.
- Check the Python version you’re using.
Resolving the errorattributeerror: module asyncio has no attribute run
is an easy task. All you have to do is update your Python version if you’re using 3.6 or below.
But before that, check first what version of Python you have or have installed in your system. To do so, open your cmd or command prompt, then enter the commandpython --version
.
This command will display the version of Python installed on your system.
Note: If you’re using version 3.6 or below, update your Python version. However, if you’re using version 3.7 or above, try to update your asyncio module. - Update the Python version.
To update your Python version, go to the Python official website and download the latest version of Python.
After installing, you can now use theasyncio.run()
function, so try to run your code again. - Update your asyncio module.
Only update your asyncio module if your Python version is compatible with it and you’re still getting the same error.
To update your asyncio module, enter the commandpip install --upgrade asyncio
.
This command will update your asyncio module to its latest version.
Alternative solution
Aside from the solutions above, there’s an alternative solution if you don’t want to update your Python version. The alternative solution is to use the loop.run_until_complete(main())
function.
Here’s an example:
import asyncio async def tutorial(): print("KEEP FIGHTING SOURCECODERS! :)") loop = asyncio.get_event_loop() loop.run_until_complete(tutorial())
Output:
KEEP FIGHTING SOURCECODERS! :)
Commands you might need
pip list
This command will display all the packages installed on your system, including their versions.
Use the!pip list

.
python -m
Include this in your installation command if you get an error message stating that “pip” cannot be found. (example:python -m pip install asyncio
)
However, if you’re using Python 3, use the commandpython3 -m pip install asyncio
