Synopsis: import portalocker file = open("somefile", "r+") portalocker.lock(file, portalocker.LOCK_EX) file.seek(12) file.write("foo") file.close() If you know what you're doing, you may choose to portalocker.unlock(file) before closing the file, but why? Methods: lock( file, flags ) unlock( file ) Constants: LOCK_EX LOCK_SH LOCK_NB I learned the win32 technique for locking files from sample code provided by John Nielsen in the documentation that accompanies the win32 modules.
