user_ids = {“teraCoder”: 9018293, “proProgrammer”: 119238}
user_ids.update({“theLooper”: 138475, “stringQueen”: 85739})

When I run the above in Codeacademy the result is:
{‘stringQueen’: 85739, ‘theLooper’: 138475, ‘teraCoder’: 9018293, ‘proProgrammer’: 119238}

When I run the same code in my text editor, the result is:
{‘teraCoder’: 9018293, ‘proProgrammer’: 119238, ‘theLooper’: 138475, ‘stringQueen’: 85739}

Why the difference in the ordering?
The output of my text editor seems more rational to me since the additions are placed after the original content of the dictionary.


because only since python 3.6 dictionaries preserve order
