wave.open()

wave.open(file, mode=None)

If file is a string, open the file by that name, otherwise treat it as a file-like object. mode can be:

'rb'

Read only mode.

'wb'

Write only mode.

Note that it does not allow read/write WAV files.

A mode of 'rb' returns a Wave_read object, while a mode of 'wb' returns a Wave_write object. If mode is omitted and a file-like object is passed as file, file.mode is used as the default value for mode.

If you pass in a file-like object, the wave object will not close it when its close() method is called; it is the caller’s responsibility to close the file object.

The open() function may be used in a with statement. When the with block completes, the Wave_read.close() or Wave_write.close() method is called.
