How can I tell if the list order changed when I sort by different properties of the list?
-1
If I have a list of dicts and I sort the list by two different keys, how can I tell if the resulting list order is the same for both keys?
For instance I have a list such as:
rename_operations = [
{'before_rename': 'DSCF_1.jpg', 'after_rename': '20181200_123112.jpg'},
{'before_rename': 'DSCF_2.jpg', 'after_rename': '20181200_123212.jpg'},
{'before_rename': 'DSCF_3.jpg', 'after_rename': '20181200_123312.jpg'},
{'before_rename': 'DSCF_4.jpg', 'after_rename': '20181200_123412.jpg'},
{'before_rename': 'DSCF_5.jpg', 'after_rename': '20181200_123512.jpg'},
]
I want to validate that in both cases sorting the list by before_rename and by after_rename yields the list in the same order.

I believe you can just use ==
rename_operations1 = [
{'before_rename': 'DSCF_1.jpg', 'after_rename': '20181200_123112.jpg'},
{'before_rename': 'DSCF_2.jpg', 'after_rename': '20181200_123212.jpg'},
{'before_rename': 'DSCF_3.jpg', 'after_rename': '20181200_123312.jpg'},
{'before_rename': 'DSCF_4.jpg', 'after_rename': '20181200_123412.jpg'},
{'before_rename': 'DSCF_5.jpg', 'after_rename': '20181200_123512.jpg'},
]
rename_operations2 = [
{'before_rename': 'DSCF_1.jpg', 'after_rename': '20181200_123112.jpg'},
{'before_rename': 'DSCF_3.jpg', 'after_rename': '20181200_123312.jpg'},
{'before_rename': 'DSCF_4.jpg', 'after_rename': '20181200_123412.jpg'},
{'before_rename': 'DSCF_5.jpg', 'after_rename': '20181200_123512.jpg'},
{'before_rename': 'DSCF_2.jpg', 'after_rename': '20181200_123212.jpg'},
]
print(rename_operations1 == rename_operations2)
>>> False
print(rename_operations1 == rename_operations1)
>>> True
