#Learning objective:
#*Recovering from a file IO run time error using exceptions
#*Note:
#   -The example is purposely as simple as possible so it doesn't handle
#   things as well as it should.
#   -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.

while(fileOK == False):
    try:
        filename = input("Name of file to open: ")
        aFile = open(filename,"r")
        for line in aFile:
            print(line,end="")
        aFile.close()
    except IOError:
        print("Problem encounted during the interaction with %s" %(filename))
    else:
        fileOK = True
print()
print("Done reading from file")
