Usually, you cannot do that: "JSON" stands for "JavaScript Object Notation": it is a text representation for a single (!) JavaScript object. The concatenation of two JSON representations is not a valid JSON representation. Thus, you cannot expect that after such a concatenation, a single call to "load" will give you back complete information (it might be that a sequence of "load"s works). Personally, I would avoid concatenated JSON representations. Instead, I would read in (i.e. "load") the existing data, construct a Python object from the old and the new data (likely in the form of a list) and then write it out (i.e. "dump") again. -- https://mail.python.org/mailman/listinfo/python-list
