Python: "as"关键字简写

Question

简单的问题:在 Python 中迭代时是否可以分配速记引用，如下所示(这不起作用):

class SomeClass:
    class_dict = {0:0,1:1,2:2,3:3}

newClass = SomeClass()

for n in newClass.class_dict as thedict: # assigning a shorthand reference "thedict" to newClass.class_dict
    print(thedict[n])

Answer 1

我想你想要这个(使用iteritems()将键/值对迭代为n, o):

class SomeClass:
    class_dict = {0:0,1:1,2:2,3:3}

newClass = SomeClass()

for n, o in newClass.class_dict.iteritems():
    print(o)
