1. python列表的字符串形式转列表形式

• 方式1：python内置函数eval()
• 方式2：literal_eval
• 方式3：json.loads()
• 方式4：str.strip("[]").split(",")

2. 示例代码

# -- encoding: utf-8 --
# @time:    	2021/4/18 12:33
# @Author: 		jsonLiu
# @Email:  		xxxxxxxxx@qq.com
# @file: 		listStrToList
import json
from ast import literal_eval
str1 = '["S-20210421-123","S-20210421-456","S-20210421-789"]'
#str = '['S-20210421-123','S-20210421-456','S-20210421-789']' # 必须是'""'或"''",否则报invalid syntax
str2 = '[S-20210421-123,S-20210421-456,S-20210421-789]'
# 方式1：python内置函数：eval
l1 = eval(str1)
print("type:%s%s" %(type(l1),l1))

# 方式2：json.loads()
l2 = json.loads(str1)
print("type:%s%s" %(type(l2),l2))

# 方式3：literal_eval
l3 = literal_eval(str1)
print("type:%s%s" %(type(l3),l3))

# 方式4：字符串拼接
l4 = str2.strip('[]').split(',')
print("type:%s%s" %(type(l4),l4))

3. 最终运行结果
