TypeError: 'set' object does not support indexing 错误解答 1. 错误原因 在Python 中,TypeError: 'set' object does not support indexing 错误表明你尝试对一个集合(set)对象使用索引操作,但集合(set)是一种无序且不重复的元素集,因此它不支持索引操作。索引操作通常用于列表(list)、元组(tuple)或字符串(str...
1:python3'set'object does not support indexing 2:q是一个字符串,而字符串是不可变对象,你不能用下标赋值的方式去改变字符串 。至于a=123 3:b=123,使用同一内存地址也很好理解 4:在python中,数字,字符串和元组都是不可变对象 5:比如字符串,如果被python判定为是短字符串,那么为了节省...
注意:创建一个空集合必须用set()而不是{},因为{}是用来创建一个空字典。 集合是无序的、不重复的、没有索引的 1a = {'hello','ni','hao','hi','ni','hao'}23print(a)#输出结果没有重复项,且无序4#print(a[1]) # TypeError: 'set' object does not support indexing 输出结果: {'ni','hao...
