Python strings, tuples, lists, dictionaries convert each other's methods

#-*-coding:utf-8-*-

#1, Dictionaries
Dict = {' name ': ' Zara ', ' age ': 7, ' class ': ' First '}

#字典转为字符串, return: <type ' str ' > {' age ': 7, ' name ': ' Zara ', ' class ': ' First '}
Print type (str (dict)), str (DICT)

#字典可以转为元组, return: (' age ', ' name ', ' class ')
Print tuple (dict)
#字典可以转为元组, return: (7, ' Zara ', ' first ')
Print tuple (dict.values ())

#字典转为列表, return: [' age ', ' name ', ' class ']
Print List (dict)
#字典转为列表
Print Dict.values

#2, tuples
tup= (1, 2, 3, 4, 5)

#元组转为字符串, return: (1, 2, 3, 4, 5)
Print tup.__str__ ()

#元组转为列表, return: [1, 2, 3, 4, 5]
Print List (TUP)

#元组不可以转为字典

#3, List
Nums=[1, 3, 5, 7, 8, 13, 20];

#列表转为字符串, return: [1, 3, 5, 7, 8, 13, 20]
Print str (nums)

#列表转为元组, return: (1, 3, 5, 7, 8, 13, 20)
Print tuple (nums)

#列表不可以转为字典

#4, String

#字符串转为元组, return: (1, 2, 3)
Print tuple (eval ("())")
#字符串转为列表, return: [1, 2, 3]
Print List (eval ("(+)"))
#字符串转为字典, return: <type ' dict ' >
Print type (eval ("{' Name ': ' Ljq ', ' Age ': 24}"))
