How to Fix the TypeError in Your Python Game Code: A Guide to Function Arguments

Are you getting an annoying TypeError in your Python game code? If you’re facing the error:

this guide will guide you through resolving this issue step by step. Let's break down what's happening in your code and how you can fix it.

Understanding the Error

At the core, the error indicates that the function helper_text_height is defined to take no arguments, but you are attempting to call it and pass an argument to it. To illustrate:

The Error Line

In the draw_messages function of your code, you have this line:

Here, you're trying to pass Constants.FONT_MESSAGE_TEXT as an argument to the helper_text_height function, which it isn't designed to accept. This mismatch between how the function is defined and how it’s called is causing your program to throw a TypeError.

Fixing the Issue

Step 1: Redefine the Function

To resolve this, you need to change the definition of helper_text_height() to accept a font parameter. Here’s how you can modify the function:

Step 2: Update Function Call

With the updated function definition, the call in draw_messages remains the same:

Now, this call will work because the function can accept the font argument you’re passing to it.

Step 3: Test Your Code

After making these changes, run your game again. The error should be resolved, and you should see the text rendered properly on the screen.

Summary

Errors like the one you're facing can often be traced back to mismatches between function definitions and their calls. In this case, changing the definition of helper_text_height to accept a font parameter fixed your TypeError. Always remember to ensure that your functions can handle the parameters you want to pass to them:

Check the function definition to see what arguments it expects.

Revise the function call accordingly to match the definition.

By implementing these steps, you can not only fix this issue, but also develop a stronger understanding of how Python functions work, making you a better programmer overall!
