python Unresolved reference

"Unresolved reference" error in Python usually occurs when you are trying to use a variable, function, or class that hasn't been defined yet. Here are some common causes and solutions:

1. Misspelled variable or function name: Check if you have spelled the name correctly.

2. Import error: If you are importing a module and getting an "Unresolved reference" error, make sure the module is installed and accessible in your environment.

3. Name collision: If you have defined a variable or function with the same name as a built-in function or module, Python can get confused. Try using a different name.

4. Circular dependencies: If you have two modules that import each other, it can cause "Unresolved reference" errors. Try restructuring your code so that there is no circular dependency.

5. Incorrect indentation: Make sure your code is properly indented, as indentation is significant in Python.

6. Scope issue: If you are trying to access a variable or function that is defined in a different scope, such as a function or class, make sure you are calling it from the correct scope.

By addressing these common issues, you should be able to resolve the "Unresolved reference" error in Python.
