Doesn't count data from the list

Hello, guys! I’m new to Python, and I have a problem. I’m trying to write a program, and for my program, I want to use a list to store data that I can access when I need it. So I’m trying to create an if statement to check if what I entered in the previous input matches any item in the list. However, it’s never matching. How can I fix that?
python code

What output in terminal(I can’t to pin it previously because i just now create the account)

When presenting code (and output), paste it into the message between triple ticks like:

```
print(a)
```

rather than using screenshots.

As to your problem, to check whether a value is found in a list, you need to use the in keyword like:

if sel_num in list_of_reg_num:
    ...
else:
    ...
