Python error: AttributeError: 'module' object has no attribute 'xxx', how to solve it?
In the process of programming in Python, we may encounter various errors. One of the common errors is AttributeError. This error is triggered when we try to access a property that does not exist in a module object. To better understand this error and its solution, let's first look at an example.
Suppose we have a module file named module_test.py with the following content:
# module_test.py def hello(): print("Hello, world!")
Now, we try to import this module and call the hello function in another Python file:
# main.py import module_test module_test.hello() module_test.world()
The output we expect is:
Hello, world!
But after running the code, we will encounter the following error message:
AttributeError: 'module' object has no attribute 'world'
This error tells us that the module object (module_test) does not have a name Properties or methods of 'world'. So, how do we solve this problem? Here are a few possible solutions.
# main.py import module_test module_test.hello()
Based on the above solution, our modified main.py code is as follows:
# main.py import module_test module_test.hello()
Now, when we run the main file main.py, we will get the correct output:
Hello, world!
Summary:
When encountering the Python error AttributeError: 'module' object has no attribute 'xxx', we should carefully check the spelling errors in the code, confirm whether the import is correct, and ensure that the module exists This property or method. Through the above solutions, we can solve this error and make our program run normally.
I hope this article can help you solve the problem of Python error AttributeError: 'module' object has no attribute 'xxx'. Good luck with your programming!
