Resolving the NameError: Understanding Python Variable Definitions
Are you encountering a frustrating NameError: name 'Doctor' is not defined message while executing your Python code? If you are, you're not alone! This common error usually occurs due to a simple oversight in variable definition. In this guide, we’ll break down the problem and guide you through a clear resolution.
The Problem: Understanding the Error
The NameError in Python signifies that you are attempting to use a variable that hasn't been defined within the current scope. In the provided code snippet, the line:

is causing the error because the variable Doctor has not been defined anywhere in the code. To clarify, let’s look at the components of the code and see how we can address this problem.
The Solution: Defining Your Variables Correctly
To resolve the issue, you must ensure that the variable you are trying to use is defined prior to its invocation. Here's how you can adjust your code effectively:
Step 1: Modify the Function Definition
The original function defined job descriptions based on numeric values. Instead, it would be more intuitive to use string values that represent job titles directly. Here’s an updated version of your function:

Conclusion
By correctly defining variables and using string values in function calls, you can avoid NameError. Python's strict variable referencing means that you must always ensure that variables are defined before they are utilized. With this knowledge, you're now equipped to tackle similar errors in your Python programming!
Remember: Always double-check your function calls and variable definitions to maintain code integrity and avoid common pitfalls like NameError.
Now that you know how to resolve this issue, go ahead and implement the changes in your code. Happy coding!
