dict={'key1':'value1','key2':'value2'} 而sequence 方法则是 Python 标准库中的一个序列类型,它可以用来表示一个序列,如: s=[1,2,3] 当我们试图对 dict 对象使用 sequence 方法时,就会引发错误类型:dict is not a sequence。 那么,我们该如何解决这个问题呢? 首先,你需要明确 dict 对象的本质,它...
在Python中,dict是一种数据结构,用于存储键值对,而sequence是一种数据结构,用于存储有序元素,如列表、元组或字符串等。然而,当尝试将dict对象赋给sequence类型时,会引发typeerror: dict is not a sequence错误。 这个错误指出,一个dict对象并不是一个sequence对象。dict对象不支持sequence对象的操作,如len()、sorted(...
