  7. Local Variable Referenced Before Assignment in Python

    We can declare the variable as global using the global keyword in Python. Once the variable is declared global, the program can access the variable within a function, and no error will occur. The below example code demonstrates the code scenario where the program will end up with the local variable referenced before assignment error.

  8. Python UnboundLocalError: local variable referenced before assignment

    If you try to reference a local variable before assigning a value to it within the body of a function, you will encounter the UnboundLocalError: local variable referenced before assignment. The preferable way to solve this error is to pass parameters to your function, for example:

  9. local variable referenced before assignment but variable is global

    1 Answer Sorted by: 1 Python treats your variable answer as a local variable as in your answerCheck () function, under the else clause, there is an assignment done to the variable answer. Since there is an assignment involved within the local scope, python treats the variable to be in the local scope and this gives your issue.

  10. How to fix UnboundLocalError: local variable 'x' referenced before

    Here's the best solution to the error: name = "Nathan" def greet(name): name_with_title = "Mr. " + name print("Hello, " + name_with_title) greet(name) Now it's clear that we're using the name variable given to the function as part of the value assigned to name_with_title. Way to go! Conclusion
