How to get around a "." in key value?

I have a file which contains key values in which I need the value of the field for the identifier in a storage. Example:

“No.”: “STUB103-727-9M”,
“Product_Number”: “STK-SHIRT”,
“Category_No”: “1907”,
“Category_Name”: “1907”

I am placing these items in a storage and would like to use the value in “No.” as the identifier in the storage. However, when I use &{No.} this gives me an error which I assume is because of the “.”.

How can I get around this?

Adding quotes around the key name seems to work.

Yeah that works! Thank you!
