Pass a string with quotation marks as variable in Python

I have a function that takes multiple string arguments in the form of e.g. Subscription(items=["A", "B", "C"]) (quotation marks are mandatory, alphabet is just an example here). I don't want to write the arguments manually so I have a loop like

string=""
for letter in alphabet.values():
   tmp="\"+letter+"\","
   string=string+tmp

print(string) #only for debugging
Subscription(items=[string])

Unfortunately, this does not work, nothing happens. However, if I copy the string printed to the console and paste it into the items=[ ], it works. So the content seems to be fine but I suspect that something about the \" formatting seems to be off when pasting the variable. I feel like I made a thinking mistake but I can't figure it out. Does anybody here have an idea?
