Python字符串、元组、列表、字典互相转换的方法
废话不多说了,直接给大家贴代码了,代码写的不好还去各位大侠见谅。
#-*-coding:utf-8-*- #1、字典 dict = {'name': 'Zara', 'age': 7, 'class': 'First'} #字典转为字符串,返回:<type 'str'> {'age': 7, 'name': 'Zara', 'class': 'First'} print type(str(dict)), str(dict) #字典可以转为元组,返回:('age', 'name', 'class') print tuple(dict) #字典可以转为元组,返回:(7, 'Zara', 'First') print tuple(dict.values()) #字典转为列表,返回:['age', 'name', 'class'] print list(dict) #字典转为列表 print dict.values #2、元组 tup=(1, 2, 3, 4, 5) #元组转为字符串,返回:(1, 2, 3, 4, 5) print tup.__str__() #元组转为列表,返回:[1, 2, 3, 4, 5] print list(tup) #元组不可以转为字典 #3、列表 nums=[1, 3, 5, 7, 8, 13, 20]; #列表转为字符串,返回:[1, 3, 5, 7, 8, 13, 20] print str(nums) #列表转为元组,返回:(1, 3, 5, 7, 8, 13, 20) print tuple(nums) #列表不可以转为字典 #4、字符串 #字符串转为元组,返回:(1, 2, 3) print tuple(eval("(1,2,3)")) #字符串转为列表,返回:[1, 2, 3] print list(eval("(1,2,3)")) #字符串转为字典,返回:<type 'dict'> print type(eval("{'name':'ljq', 'age':24}"))
