python 字符串和json互相转换学习笔记

 代码：

a = [{"value": "22", "label": "吉林省"}, {"value": "2206", "label": "白山市"}, {"value": "220622", "label": "靖宇县"}]
print(a)
print(type(a))
# 将json转换成字符串
b = json.dumps(a, ensure_ascii=False)
print(b)
print(type(b))
# 去掉字符串的空格然后输出
print(''.join(b.split()))
abc = "[{\"value\":\"22\",\"label\":\"吉林省\"},{\"value\":\"2206\",\"label\":\"白山市\"},{\"value\":\"220622\",\"label\":\"靖宇县\"}]"
print(abc)
print(type(abc))
if ''.join(b.split()) == abc:
    print(True)
else:
    print(False)
# 将字符串转换成json
d = json.loads(abc)
print(d)
print(type(d))
if a == d:
    print(True)
else:
    print(False)

运行结果：
