python 兩個列表添加

Question

有一組列表，a,b,c,…，想要將這一組列表不斷加到同一個列表裡面，例如:

`a = ['a']
b = ['b']
c = ['c']
addall = [['a'], ['b'], ['c']]`

只想到了用for迴圈來做這個，有什麼比較pythonic的方法麼？

Answer 1

沒必要太在意形式，簡潔易懂就行

a = ['a']
b = ['b']
c = ['c']
tt=[]
tt.append(a)
tt.append(b)
tt.append(c)
print tt
#输出[['a'], ['b'], ['c']]

Answer 3

python2,3

In [6]: a=['a']

In [7]: b=['b']

In [8]: a.extend(b)

In [9]: a
Out[9]: ['a', 'b']

python2,3,我覺得這樣比較自然!

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']

Answer 4

d = [i 代表 (a,b,c) 中的 i]
