How do I modify a text file in Python? | 125,703 | <p>I'm using Python, and would like to insert a string into a text file without deleting or copying the file. How can I do that?</p>
| 125 | 2008-09-24T06:30:56Z | 130,844 | <p>Python's mmap module will allow you to insert into a file. The following sample shows how it can be done in Unix (Windows mmap may be different). Note that this does not handle all error conditions and you might corrupt or lose the original file. Also, this won't handle unicode strings.</p>
