Python 访问正确的循环值

Question

我有 ：

data = [ {"Bucket": "test", "MountPoint": "/data"}, {"Bucket": "test2", "MountPoint": "/data2"} ]

我使用这个循环来访问我的值Bucket和MountPoint列表。

my_vals = [val for d in data for val in d.values()]

>>> print(my_vals)

['/data', 'test', '/data2', 'test2']

但有了这个，我把Bucket和MountPoint我的列表中。现在，我怎么能仅MountPoint通过修改我的 for就将其放入我的列表中？

Answer 1

列表理解（迭代字典）是一种可能性：data = [ {"Bucket": "test", "MountPoint": "/data"}, {"Bucket": "test2", "MountPoint": "/data2"} ]buckets = [d["Bucket"] for d in data]      # ['test', 'test2']mpoints = [d["MountPoint"] for d in data]  # ['/data', '/data2']
