I'm using Python 3.6. I wrote a simple function:

```
def data(filename, file):
    data(filename=input(), file=open(filename))
    return file.read()

print(data)

```

and got an error like this:

> 
> "C:\Users\Jack The Reaper\Anaconda3\python.exe" "C:/Users/Jack The
>  Reaper/Documents/untitled/untitled.py" 
> 
> 
> Process finished with exit code 0
> 
> 
> 

I don't have any idea what is going on, please explain.
