方法1.
import ast str_ = "['hello','world']" list_ = ast.literal_eval(str_) ###补充### ###函数eval貌似等效于ast.literal_eval ###list__ = eval(str_)输出效果与list_ = ast.literal_eval(str_)相同 print(str_,list_) print(type(str),type(list_))执行结果
['hello','world'] ['hello', 'world'] <class 'str'> <class 'list'>方法2.
str_ = "['hello','world']" list_ = list(str_) print(str_,list_) print(type(list_))执行结果
['hello','world'] ['[', "'", 'h', 'e', 'l', 'l', 'o', "'", ',', "'", 'w', 'o', 'r', 'l', 'd', "'", ']'] <class 'list'>方法3.
import json ###引号一定要注意 ###外边单引号，里边双引号 str_ = '["halo","world"]' list_ = json.loads(str_) print(list_) print(type(list_))执行结果
['halo', 'world'] <class 'list'>参考
