THONNY IMPORT MODULE CODE

This code will throw the following error: ModuleNotFoundError: No module named 'demoA.test' The following code will throw a module not found error: import demoA.test as test1 Here are the contents of test1.py: def hello():Īnd let's say you want to use this declared hello function in test2.py.

In it, you have two folders demoA and demoB.ĭemoA has an _init_.py file (to show it's a Python package) and a test1.py module.ĭemoA also has an _init_.py file and a test2.py module. Let's say you have a project folder called test. When you try to access a module from the wrong path, you will also get the module not found here. For this example, I'll focus on absolute paths. In Python, you can import modules from other files using absolute or relative paths. You can fix this error by spelling the module in the right casing. Here's an example: import Numpy as npįor this code, you have numpy installed but running the above code will throw this error: ModuleNotFoundError: No module named 'Numpy'ĭue to casing differences, numpy and Numpy are different modules. Similar to the misspelling issue for module not found errors, it could also be that you are spelling the module correctly, but in the wrong casing. Make sure modules are in the right casing You can fix this error by spelling the module correctly. This error comes as a result of the misspelled numpy module as nompy (with the letter o instead of u). Here, you have installed numpy but running the above code throws this error: ModuleNotFoundError: No module named 'nompy' Take, for example, this code: import nompy as np In such cases, it could be that you spelled it incorrectly. In some cases, you may have installed the module you need, but trying to use it still throws the ModuleNotFound error. When installed, the previous code will work correctly and you get the result printed in your terminal: Ģ.

THONNY IMPORT MODULE INSTALL

You can install the module like this: python -m pip install numpy Then it's most likely possible that the numpy module is not installed on your device. If you try to run this code with python test.py and you get this error: ModuleNotFoundError: No module named 'numpy' You use this module in your code in a file called 'test.py' like this: import numpy as np

THONNY IMPORT MODULE HOW TO

How to fix the ModuleNotFoundError in PythonĪs I mentioned in the previous section, there are a couple of reasons a module may not be found.

you are importing a module using the wrong path.

you use an incorrect casing for a module (which still links back to the first point).for example, spelling numpy as NumPy during import will throw the module not found error as both modules are 'not the same'.

you spelled a module incorrectly (which still links back to the previous point, that the misspelled module is not installed).for example, spelling numpy as numpys during import.

you do not have the module you tried importing installed on your computer.

Here are a few reasons why a module may not be found:

Here's an error when I try to import a numpys module that cannot be found: import numpys as np In the case of the title, the 'module named Python' cannot be found. What does this error mean in Python?Īs the name implies, this error occurs when you're trying to access or use a module that cannot be found. Sometimes, Python throws the ModuleNotFoundError afterward. When you try to import a module in a Python file, Python tries to resolve this module in several ways.
