dict() function isn't working properly on the cloud server (Python3)

Hi, i’m having problem using python3 on my Ubuntu 16.04.3 x64 with the dict() function when i use it on my own PC it works fine but on the cloud server isn’t running well…

after sorting my dictionary with sotred() function i get this output (example):

[(1, {'car': 'red'}, 2, {'bike': 'green'}, 3, {'plane': 'white'})]

when i want it to turn the tuple to dictionary i use dict() (example):

dict([(1, {'car': 'red'}, 2, {'bike': 'green'}, 3, {'plane': 'white'})])

but when use the dict function it reorder everything randomly (example):

{2, {'bike': 'green'}, 3, {'plane': 'white'}, 1, {'car': 'red'}}

any idea why?

Python’s dict is not guaranteed to return items in the same order. Try something like this if required:

#!/usr/lib python3
from collections import OrderedDict

L = {3: {'iphone': 5}, 2: {'iphone': 4}, 4: {'iphone': 3}, 5: {'iphone': 6}, 6: {'iphone': 7}, 7: {'iphone': 1}, 8: {'iphone': 2}}

# Sort dict on iphone numbers
T = sorted(L.items(), key=lambda y: int(y[1]['iphone']))
#print(T) # print to check the result of sorted function

D = OrderedDict(T)
print(D) # check the tuple after changed to dictionary
