AttributeError: 'str' object has no attribute 'write'

Question

I'm working on Python and have defined a variable called "_headers" as shown below

_headers = ('id',                 'recipient_address_1',                 'recipient_address_2',                 'recipient_address_3',                 'recipient_address_4',                 'recipient_address_5',                 'recipient_address_6',                 'recipient_postcode',                 ) 

and in order to write this into an output file, I've written the following statement but it throws me the error "AttributeError: 'str' object has no attribute 'write'"

with open(outfile, 'w') as f:               outfile.write(self._headers)               print done 

Please help

Answer 1

You want f.write, not outfile.write...

outfile is the name of the file as a string. f is the file object.

As noted in the comments, file.write expects a string, not a sequence. If you wanted to write data from a sequence, you could use file.writelines. e.g. f.writelines(self._headers). But beware, this doesn't append a newline to each line. You need to do that yourself. :)

Answer 2

Assuming that you want 1 header per line, try this:

with open(outfile, 'w') as f:     f.write('\n'.join(self._headers))       print done
