wierd console behaviour when having multiple lines of code

When i am trying to run this:

```
print("hello world!")
```

everything works just like expected (I get "hello world!" printed out in the console that pops up below) . However, if i am running any of these:

```
print("hello world!")

```

or (notice that there is a blank line on both of these ^ v)

```

print("hello world!")
```

or

```
print("hello world!")
print("something")
```

that console is just empty.

Before I try to reinstall atom, i wanted to ask if anybody here knows/ has an idea of what is going on, it could very well be that i am just plain stupid an ignoring something pretty obvious... :P
