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
Sample output with inputs: 5.0 10.0 3.0 7.0
max_sum is: 17.0

Transcribed Image Text: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.
