一道Python面试题的几种解答: 两个元祖T1=('a', 'b'), T2=('c', 'd'),请使用匿名函数将其转变成[{'a': 'c'}, {'b': 'd'}]
方法一:
1
2
3

|
>>> T1 = ( 'a' , 'b' ) >>> T2 = ( 'c' , 'd' ) >>> list ( map ( lambda x:{x[ 0 ]:x[ 1 ]}, zip (T1, T2))) [{ 'a' : 'c' }, { 'b' : 'd' }] |
方法二:
1
2
3
4
|
>>> T1 = ( 'a' , 'b' ) >>> T2 = ( 'c' , 'd' ) >>> [{v1:v2} for (i1,v1) in enumerate (T1) for (i2,v2) in enumerate (T2) if i1 = = i2] [{ 'a' : 'c' }, { 'b' : 'd' }] |
方法三:
1
2
3
4
5
|
>>> T1 = ( 'a' , 'b' ) >>> T2 = ( 'c' , 'd' ) >>> ret = lambda t1,t2:[{x:y} for x in t1 for y in t2 if t1.index(x) = = t2.index(y)] >>> ret(T1, T2) [{ 'a' : 'c' }, { 'b' : 'd' }] |
方法四:
1

5
|
>>> T1 = ( 'a' , 'b' ) >>> T2 = ( 'c' , 'd' ) >>> ret = lambda t1,t2:[{x,y} for (x,y) in zip (t1, t2)] >>> ret(T1, T2) [{ 'a' , 'c' }, { 'd' , 'b' }] |
方法五:
1
2
3
4
5
|
>>> T1 = ( 'a' , 'b' ) >>> T2 = ( 'c' , 'd' ) >>> ret = lambda t1,t2:[{t1[i]:t2[i]} for i in range ( len (t1))] >>> ret(T1, T2) [{ 'a' : 'c' }, { 'b' : 'd' }] |
方法六:

|
>>> T1 = ( 'a' , 'b' ) >>> T2 = ( 'c' , 'd' ) >>> list ( map ( lambda x,y:{x:y}, T1, T2)) [{ 'a' : 'c' }, { 'b' : 'd' }] |
