a = {'a' : '1', 'b' : '2'}

print('字典的值为: %s' % list(a.values()))
print("字典的值为: %s" % str(tuple(a.values())))

请问为什么tuple要加str?
新手求帮助！嘎嘎新

我以为list()返还的是str,结果看了下type, 是list
tuple()的type 是 tuple
tuple就不是str吗

==============================================================
a = {'a' : '1', 'b' : '2'}

print('字典的值为: %s' % list(a.values()))
print("字典的值为: %s" % str(tuple(a.values())))

b = list(a.values())
c = tuple(a.values())

print(type(b))
print(type(c))

结果：==================================
字典的值为: ['1', '2']
字典的值为: ('1', '2')
<class 'list'>
<class 'tuple'>
