有一組列表，a,b,c,……，想要將這一組列表不斷添加到同一個(gè)列表里面，比如:
`a = ['a']
b = ['b']
c = ['c']
addall = [['a'], ['b'], ['c']]`
只想到了用for循環(huán)來做這個(gè)，有什么比較pythonic的方法么？

沒必要太在意形式，簡潔易于理解就行
a = ['a']
b = ['b']
c = ['c']
tt=[]
tt.append(a)
tt.append(b)
tt.append(c)
print tt
#輸出[['a'], ['b'], ['c']]
python2,3
In [6]: a=['a']
In [7]: b=['b']
In [8]: a.extend(b)
In [9]: a
Out[9]: ['a', 'b']
python2,3,我覺得這個(gè)比較自然!
In [1]: a=['a']
In [2]: b=['b']
In [3]: a+b
Out[3]: ['a', 'b']
python3
In [1]: a=['a']
In [2]: b=['b']
In [3]: [*a,*b]
Out[3]: ['a', 'b']
