io.UnsupportedOperation: not writable - variable name is the same [duplicate]

Question

So this is my code snippet. I keep getting the error "io.UnsupportedOperation: not writable"

outputfile = open("output.txt")
for line in lines:
    outputfile.write(line)

outputfile.close()

By default, open() opens files for reading, not writing. To open a file for writing, you need to specify 'w' as the mode:

outputfile = open("output.txt", 'w')
