#Learning objective:
#*Recovering from a file IO run time error using exceptions
#*Note:
#   -The example is as simple as possible which is why it doesn't handle
#   things as well as it should e.g. it just tells the user about the error
#   but doesn't do anything else.
#   -But it won't crash if problems occur during the opening, reading or
#   even the closing of the file.


#Trying to open or read from a file may result in an exception being raised.

    aFile = open("input.txt","r")
    print(aFile.readline())
    aFile.close()
