The Input and Output section of the Python 3.0 tutorial (http://docs.python.org/dev/3.0/tutorial/inputoutput.html) shows an example of seeking in a negative direction from the end of a file. I get an IOError when attempting to run the example in Python 3.0b2 on Mac OS X 10.4 (PPC). I don't know whether the tutorial or the code should be changed. >>> f = open('workfile', 'r+') >>> f.write('0123456789abcdef') 16 >>> f.seek(-3, 2) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Users/jimsize/Programming/Python/py3k/3.0b2/lib/python3.0/io.py", line 1609, in seek raise IOError("can't do nonzero end-relative seeks") IOError: can't do nonzero end-relative seeks |

Since the file is a text file, such seeking is not possible. I've now updated the whole section about files; in particular there was also an outdated description of text vs. binary mode. Committed r65595. |
