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:
>>> T1 = ('a', 'b')
>>> T2 = ('c', 'd')
>>> list(map(lambda x:{x[0]:x[1]}, zip(T1, T2)))
[{'a': 'c'}, {'b': 'd'}]
方法二:
>>> 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:
>>> 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:
>>> 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:
>>> 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'}]
