i keep getting unordered output when using dictionaries

[fuadfzy]

Hello guys, i'm new here. please go easy on me

i got a quite dummy question to ask. when i used the dictionaries data structure, i keep getting the output randomly ordered. this is the example of it:

content_ratings = {'4+': 4433, '9+': 987, '12+': 1155, '17+': 622}

print(content_ratings)

and the output will be:

Output:
{'9+': 987, '4+': 4433, '12+': 1155, '17+': 622}

i don't know how the index are not the same with the way i write the code. it's quite confusing. thank you in advance guys
