python中dict.get

在Python中，dict.get()函数用于获取字典中指定键的值。这个函数接受两个参数，第一个参数是要获取值的键，第二个参数是可选的默认值，用于在指定键不存在时返回该默认值。例如，如果我们有一个字典dict = {'Name': 'Runoob', 'Age': 27}，可以使用dict.get('Age')来获取键为'Age'的值，返回27。如果键不存在，可以通过传递第二个参数来返回一个默认值，如dict.get('Sex', "Not Available")，将返回"Not Available"。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
