如果我有字典列表,并按两个不同的键对列表进行排序,那么如何确定两个键的结果列表顺序是否相同?
例如,我有一个列表,例如:
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'},
]
我想验证一下,在两种情况下都按before_rename
和after_rename
对列表进行排序会以相同的顺序产生列表。

我相信您可以只使用==
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
