the print was only to see if it was reading correct data but iìm not 
needing to see it.

the file esclusioni.txt has the names of the market places that i want to 
exclude ... the correspoding marketplace name is found in the symbol 
value of the json imported data, that's why i'm comparing it with symbol.

>> esclusioni.close()

that's a nice approach ( if d["symbol"] not in esclusioni: )!!!

Thanks i will give it a try ... i was getting crazy and my mind was 
looping dangerously!  :-)
