AttributeError: Module Object Missing Attribute
When attempting to import two modules with mutual references, you may encounter this error: "AttributeError: 'module' object has no attribute [duplicate]". This often occurs when the module structure is dependent on each other, resulting in a circular reference.
Explanation
In the provided code, module 'a.py' attempts to import 'b.py', and within 'b.py', there's an import of 'a.py'. This creates a circular dependency, causing Python to raise the "AttributeError".
Solution
To resolve this issue, avoid mutual imports within the top-level module. Instead, use functions to import modules when necessary.
Example in Python
Before:
<code class="python"># a.py import b # b.py import a</code>
After:
<code class="python"># a.py def call_b(): import b b.hi() # b.py def hi(): print("hi")</code>
This way, 'a.py' no longer imports 'b.py' at the top level, and the circular dependency is broken.
