一、Python3多維元組全部轉換成列表
a = ((1,2,3),(4,5,6,),(7,8,9))
b = list(a)
print(b)
for c in b:b[b.index(c)] = list(c)
print(b)
二逛薇、list()捺疼、tuple()、join()
1.list()方法是把str或元組轉換成列表
2.tuple()方法是把str或列表轉換成元組
>>>a="abcde"
>>>list(a)
['a','b','c','d','e']
>>>tuple(a)
('a','b','c','d','e')
>>>tuple(list(a))
('a','b','c','d','e')
>>>list(tuple(s))
['a','b','c','d','e']
3. join函數(shù)是把列表和元組轉換成str
>>> " ".join(tuple(a))
'abcde'
>>> " ".join(list(a))
‘a(chǎn)bcde’
>>>str(tuple(a))
"('a','b','c','d','e')"
