字典(dict)删除元素, 可以选择两种方式, dict.pop(key)和del dict[key].
代码
:r = dict(d)del r[key]return rx = {1: 2, 3: 4, 4: 3, 2: 1, 0: 0}x.pop(1)print xx = {1: 2, 3: 4, 4: 3, 2: 1, 0: 0}del x[1]print xx = {1: 2, 3: 4, 4: 3, 2: 1, 0: 0}print remove_key(x, 1)print x”””输出:{0: 0, 2: 1, 3: 4, 4: 3}{0: 0, 2: 1, 3: 4, 4: 3}{0: 0, 2: 1, 3: 4, 4: 3}{0: 0, 1: 2, 2: 1, 3: 4, 4: 3}”””
