if num == 7:
NameError: name 'num' is not defined. Did you mean: 'sum'?

This error occurs because the variable "num" has not been defined before it is used in the if statement. The error message suggests that you might have meant to use the variable "sum" instead.

To fix this error, you need to define the variable "num" before using it in the if statement. For example:

num = 7
if num == 7:
# continue with the code

Alternatively, if you intended to use the variable "sum" instead of "num", make sure to replace all instances of "num" with "sum" in your code.

doesnt work

I apologize for the confusion in my previous response. Let's take a closer look at your code snippet and explore possible solutions.

The error message states that the variable 'num' is not defined, and it suggests that you might have meant to use the variable 'sum' instead. The error occurs when the code reaches line 8.

To fix the error, you can either define the variable 'num' or replace it with 'sum', depending on the intention of your code. Here are two potential solutions:

Solution 1: Define the variable 'num'
```python
num = 7
if num == 7:
# continue with the code
```

Solution 2: Replace 'num' with 'sum'
```python
sum = 7
if sum == 7:
# continue with the code
```

Choose the solution that aligns with your desired logic and ensure that you properly define or use the correct variable in your code.
