Python: saving objects and using pickle. extension of filename

Question

Hello I´m trying using the next piece of code:

import pickle  object = Object()  filehandler = open(filename, 'w')  pickle.dump(object, filehandler)  

I would like to know what should be the extension of the file 'filename'. Thank you!

Answer 1

You could use any filename, but as an FYI it's common to use ".p" (for obvious reasons).

pickle.dump( favorite_color, open( "save.p", "wb" ) )

Answer 2

One more thing you should pay attention to:

you should used binary mode with operation of pickling files. So 'w' should be 'wb'.
