在python中，列表，元组，字典，字符串之间是可以互相转换的

Posted 2021-01-17

list1=[‘name‘,‘age‘,‘address‘]
 
print(‘把列表list1转换为字符串:‘,str(list1))
print(type(str(list1))

str=‘wuya name sex age‘ 
print (‘把字符串str转换为列表:‘,str.split(‘ ‘))
print(‘类型为:‘,type(str.split(‘ ‘))

print (‘把列表list1转换为元组:‘,tuple(list1))
print(‘类型为:‘,type(tuple(list1))

tuple1=(‘android‘,‘ios‘,‘windows‘,‘firefoxos‘)
print (‘把元组tuple1转换为列表:‘,list(tuple1))
print（‘类型为:‘,type(list(tuple1))
 
dict1={‘name‘:‘wuya‘,‘age‘:18,‘address‘:‘xian‘}
print （‘把字典dict1转换为列表:‘,list(dict1.items())
print(‘类型为:‘,list(dict1.items())
[(‘name‘, ‘wuya‘), (‘age‘, 18), (‘address‘, ‘xian‘)]

dict1={‘name‘:‘wuya‘,‘age‘:18,‘address‘:‘xian‘}
print （‘把字典dict1转换为tuple:‘,tuple(dict1.items())
print(‘类型为:‘,tuple(dict1.items())
((‘name‘, ‘wuya‘), (‘age‘, 18), (‘address‘, ‘xian‘))

list2=list(dict1.items()) print (‘把列表转换为字典:‘,dict(list2))
print(‘类型为:‘,type(dict(list2))
{‘name‘: ‘wuya‘, ‘age‘: 18, ‘address‘: ‘xian‘}

tuple2=tuple(dict1.items()) print (‘把tuple转换为字典:‘,dict(typle2))
print(‘类型为:‘,type(dict(tuple2))
{‘name‘: ‘wuya‘, ‘age‘: 18, ‘address‘: ‘xian‘}

print (‘把列表list1转换为字典:‘,dict(enumerate(list1))
print(‘类型为:‘,dict(enumerate(list1))
{0: ‘ooo‘, 1: ‘uuu‘, 2: ‘tttt‘}
