I'd like to open a csv called x with the file name "blah.csv" in a folder.

```
import csv
def amread(x):
    with open('x', newline='') as f:
        reader = csv.reader(f)
        for row in reader:
            print(row)
            return;

```

> 
> amread() returns name blah.csv is not defined
> 
> 
> 

due to the lack of clarity, here is a full unedited quotation from the interaction pane:

```
>>> import csv
>>> def amread(x):
...     with open('x', newline='') as f:
...             reader = csv.reader(f)
...             for row in reader:
...                     print(row)
...                     return;
... 
>>> amread(blah.csv)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'blah' is not defined

```
