5 introduced the with statement as something you can import from _ _ future_ _. Since your code is correct, the only explanation I can think of is that your python version is not what. The exact error message you get is strong evidence that you are running the code on Python 2. 1 with open( inputFileName, ' rU' ) as inputFile, open ( outputFileName, ' w' ) as outputFile: ^ SyntaxError: invalid syntax. The only way I can get a SyntaxError: invalid syntax on a return statement, is if in fact it doesn' t say return at all, but if it. It doesn' t explain the 44 f = open( filename, ' r' ), but I suspect that someone copied and pasted 45 lines of. Most likely, you are using an earlier version of Python that doesn' t support the with statement.

That' s why the syntax for programming languages are so much more rigid than those. However, they all seem to be caused by using a pre- 2. 6 version of Python.

This syntax error is being thrown because the code lacks a closing parentheses " ) ". Therefore the next line is throwing the interpreter an error because your previous statement is not complete. This happens frequently. File " < stdin> ", line 42 f. close( ) ^ SyntaxError: invalid syntax. In this line I' m only closing the file! Could anyone help me please? This is the python code. import urllib2 from BeautifulSoup import BeautifulSoup # Create/ open a file.
