獲取嵌套字典值的安全方法 - Safe method to get value of nested dictionary

問題：

I have a nested dictionary.我有一個嵌套字典。 Is there only one way to get values out safely?只有一種方法可以安全地獲取值嗎？

try:
    example_dict['key1']['key2']
except KeyError:
    pass

Or maybe python has a method like get() for nested dictionary ?或者 python 有一個像get()的嵌套字典的方法？
