The method has a docstring that is not descriptive enough. The docstring should mention the variables and their descriptions to improve the code.

There should be an additional variable defined at the beginning to store the sum, and this value is returned at the end.

The name of this method should be more descriptive. It could be renamed to "calculate_sum" or "sum_nums" to better reflect its purpose.
The docstring should be updated to include more information about the parameters. For example, it could be modified to say "Finds and returns the sum of two numbers: num1 and num2."
Instead of just printing the sum onscreen, it would be better to return the sum as a result. This allows the caller of the method to decide how to handle the result, whether it's printing it, storing it in a variable, or performing further calculations with it.
Additionally, it seems that there is a typo in the parameters. "num_2" should be corrected to "num2" to match the variable name used in the function body.
Here's an improved version of the code:
def calculate_sum(num1, num2):
'''
Finds and returns the sum of two numbers: num1 and num2
'''
sum_nums = num1 + num2
return sum_nums
To evaluate the code and suggest ways to improve it, let's start by looking at the code provided:
```python
def find_sum(num1, num_2):
'''
Finds and returns sum of two numbers
'''
return num1 + num_2
```
1. The docstring: The docstring provided is not descriptive enough. It should mention the variables and their descriptions to provide clarity. For example:
```python
def find_sum(num1, num_2):
'''
Finds and returns the sum of two numbers.
Args:
num1 (int): First number to be added.
num2 (int): Second number to be added.
Returns:
int: The sum of num1 and num2.
'''
return num1 + num_2
```
2. Returning vs printing: The code currently returns the sum of the two numbers. Whether to return or print the sum depends on the intended use of the function. If the goal is to use the sum in further calculations or assignments, returning is appropriate. However, if the goal is to display the sum directly to the user, printing is preferred. If we want to print the sum, we can modify the code as follows:
```python
def find_sum(num1, num_2):
'''
Finds and prints the sum of two numbers.
'''
print(num1 + num_2)
```
3. Additional variable: Currently, the code directly returns the sum without storing it in a separate variable. Depending on the use case, it may be desirable to store the sum in a variable before returning it. Here's an example:
```python
def find_sum(num1, num_2):
'''
Finds and returns the sum of two numbers.
'''
sum = num1 + num_2
return sum
```
4. Method name: The name of the method, `find_sum`, accurately describes the functionality. However, if the function has broader functionality beyond just finding the sum, a more descriptive name might be appropriate. Consider evaluating if `find_sum` accurately conveys the purpose of the function based on its broader context.
By considering these suggestions, you can improve the code to be more readable, maintainable, and better aligned with your specific use case.

Possible suggestions to improve the code:
1. The docstring is not descriptive enough. To improve the code, it should mention the variables and their descriptions, such as:
```python
def find_sum(num1, num2):
'''
Finds and returns the sum of two numbers.
Parameters:
- num1: First number.
- num2: Second number.
'''
return num1 + num2
```
2. Instead of returning the sum, the program could just print it onscreen. This can be done by using the `print` function:
```python
def find_sum(num1, num2):
'''
Finds the sum of two numbers and prints it onscreen.
Parameters:
- num1: First number.
- num2: Second number.
'''
sum = num1 + num2
print("Sum:", sum)
```
3. There should be an additional variable defined at the beginning to store the sum, and this value is returned at the end. This can be done as follows:
```python
def find_sum(num1, num2):
'''
Finds and returns the sum of two numbers.
Parameters:
- num1: First number.
- num2: Second number.
'''
sum = num1 + num2
return sum
```
4. The name of this method should be something else. The name `find_sum` is not very descriptive. Consider renaming it to something like `calculate_sum` or `add_numbers`.
