组合数据类型综合练习

字符串联系:

t1=['ab','bc','cd']
for i in t1:
    print(i)

结果:

列表:

lis = list(t1)
lis.append(list('132456'))
for i in lis:
    print(i)

结果:

元组:

tur = ('uu', 'ee', 'eee')
tur
('uu', 'ee', 'eee')
for i in tur:
    print(i)

结果:

 

字典:

classmates = ['Michael', 'Bob', 'Tracy','Boc' ,'Tracy']
score=[90,100,80,88,99]
d=dict(zip(classmates ,score))
d1 = dict(zip('cvb', 'wer'))
dict={'a'}
dict1={}

dit = {}
dit['nacy'] = 90
dit['jacky'] = 99
dit
{'nacy': 90, 'jacky': 99}

dit.items()
dict_items([('nacy', 90), ('jacky', 99)])

dit.keys()
dict_keys(['nacy', 'jacky'])

for i in dit:
print(i)

print(d)
print(d['Tracy'])
print(d1)
print(dict,dict1)

结果:

 

 集合:

con = {'a', 'b', 'c'}
con.add('v')
{'c', 'b', 'a', 'v'}
# con = set('boy')
print(con)
con = {'a', 'b', 'c','c'}
con_set = set(con)
print(con)

结果:
