Troubleshooting: Error occurs when running the script below (code):

          Move files from one directory to another (the file must already exist)
Error is:          
          File "C:/GlobalSino2/ICs/page4853movFiles5.py", line 16, in <module>
          os.rename(source, destination)
          FileNotFoundError: [WinError 2] The system cannot find the file specified: 'C:\\Users\\yyliao\\Downloads\\AAPL.csv' -> 'C:\\0Python\\Stocks\\IndividualStocks\\AAPL.csv'         
Correct script (code):
