#1. Dictionaries

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

#字典转换为字符串, return: <type ' str ' > {' age ': 7, ' name ': ' Zara ', ' class ': ' First '}

Print (Type (str (dict)), str (DICT))

#字典可以转为元祖, return: (' age ', ' name ', ' class ')

Print (Tuple (dict)

#字典可以转为元祖, 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. Yuan zu

Tup = (1,2,3,4,5)

#元祖转为字符串, return: (1,2,3,4,5)

Print (tup.__str__ ())

#元祖转为列表, return: [1,2,3,4,5]

Print (list (tup))

#元祖不可以转为字典

#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))

#列表转为元祖, return: (1,3,5,7,8,13,20)

Print (tuple (nums))

#列表不能转为字典



#4. String

#字符串转为元祖, return: (+/-)

Print (Tuple (' All-in-all '))

#字符串转为列表, return: [+]

Print (List ("eval"))

#字符串转为字典, return: <type ' dict ' >

Print (Type (eval ("{' Name ': ' SRX ', ' age ': ' 41 '}"))
