Python基础语法(八)--类型转换

1.字符串转列表

str1 = '你 是 不 是 我 最 疼 爱 的 人'
new_str = list(str1.split())
print('字符串转列表',new_str,type(new_str))

2.列表转字符串

lis = ["你","是","不","是","我","最","疼","爱","的","人"]
new_lis = ''.join(lis)
print('列表转字符串',new_lis,type(new_lis))

3.字符串转字典

str2 = '{"name":"老王","age":18,"addr":"长沙" }'
new_dict = eval(str2)
print('字符串转字典',new_dict,type(new_dict))

4.字典转字符串

dict1 = {"name":"老王","age":18,"addr":"长沙" }
new_str1 = str(dict1)
print('字典转字符串',new_str1,type(new_str1))

5.列表合并字典

list1 = ["姓名","年龄","地址"]
list2 = ["老王",18,"北京"]
list3 = dict(zip(list1,list2))
print('合并后的字典',list3,type(list3))

6.字典拆分为列表

dic1 = {"name":"老王","age":18,"addr":"长沙" }
list_key = list(dic1.keys())
list_value = list(dic1.values())
print('key列表为:{}\nvalue列表为:{}'.format(list_key,list_value))
