Store multiple dictionaries in a file

[Philipp H. Mohr]

Hello,

I would like to store multiple dictionaries in a file, if possible one per
line. My code currently produces a new dictionary every iteration and
passes it on to another peace of code. In order to be able to re-run some
experiments at a later date I would like to store every dictionary in the
same file.
I looked at pickel, but that seems to require a whole file for each
dictionary.

It would be great if some one could tell me how to do that.

Thank you,
Phil
