Hi Rene and staff,  
you don’t talk about CSV with python, so may i ask a question about python with CSV format in this section ?  
Example 1: let’s python read a csv file

 ![image](https://cdn-forum.networklessons.com/uploads/default/original/2X/6/6e7ed8c20c38eef173c196c7808b3d0000d1bbc9.png)

Exemple1 is a string, then apply csv.reader(): you get an object “\_csv.reader” but this is not a loop object

Example 2: just open the csv file

f is a \_io.TextIOWrapper object, then apply csv.reader(): you get an object “\_csv.reader” as well, but THIS IS a loop object

I don’t understand why in example 1, a “\_csv.reader” object is NOT a loop object, and in example 2, the same object (same class) is a loop object.  
So the same object seems to be not consistent as it comes from a string or a \_io.TextIOWrapper object.  
Could you help me ?  
Best regards
