CHALLENGE ACTIVITY
6.5.1: Function call in expression.
 
Assign max_sum with the greater of num_a and num_b, PLUS the greater of num_y and num_z. Use just one statement. Hint: Call find_max() twice in an expression.

Sample output with inputs: 5.0 10.0 3.0 7.0
max_sum is: 17.0
The image contains a Python code snippet for a function that finds the maximum of two numbers. Below is a transcription of the code, which is designed to be user-friendly for educational purposes.

```python
def find_max(num_1, num_2):
    max_val = 0.0
    
    if (num_1 > num_2):  # if num1 is greater than num2,
        max_val = num_1  # then num1 is the maxVal.
    else:                # Otherwise,
        max_val = num_2  # num2 is the maxVal.
    return max_val

max_sum = 0.0

num_a = float(input())
num_b = float(input())
num_y = float(input())
num_z = float(input())

''' Your solution goes here '''
```

### Explanation of the Code

1. **Function Definition**: 
   - `find_max(num_1, num_2)`: This function takes two arguments, `num_1` and `num_2`. It finds and returns the maximum of these two numbers.

2. **Variable Initialization**: 
   - `max_val = 0.0`: Initializes a variable `max_val` to store the maximum value found between `num_1` and `num_2`.

3. **Conditional Logic**: 
   - An `if` statement checks if `num_1` is greater than `num_2`. If so, `max_val` is assigned the value of `num_1`. Otherwise, `max_val` is assigned the value of `num_2`.

4. **Return Statement**: 
   - `return max_val`: The function returns the maximum value, which is stored in `max_val`.

5. **User Input**: 
   - The code reads four floating-point numbers from the user, stored in `num_a`, `num_b`, `num_y`, and `num_z`.

6. **Comment**:
   - `''' Your solution goes here '''`: A placeholder for additional code or solution.

7. **Execution**: 
   - At the bottom, there's an interactive "Run" button to execute the code.

### Diagram/Graph Explanation

There are no diagrams or graphs included in this code snippet; it is purely textual. 

This code is ideal for educational use, especially for understanding basic functions and conditional logic in Python.
