python 内建函数 zip

key = [key for key in dict(zip(('a','b','c','d','e'),(1,2,3,4,5))) ]
print(key)
--------------------------------------------------------
['a','e']

A0 = dict(zip(('a',5)))
A1 = range(10)
A2 = [i for i in A1 if i in A0]
A3 = [A0[s] for s in A0]
A4 = [i for i in A1 if i in A3]
A5 = {i:i*i for i in A1}
A6 = [[i,i*i] for i in A1]
-------------------------------------------------------------
A0 = {'a': 1,'c': 3,'b': 2,'e': 5,'d': 4}
A1 = [0,1,5,6,7,8,9]
A2 = []
A3 = [1,4]
A4 = [1,5]
A5 = {0: 0,1: 1,2: 4,3: 9,4: 16,5: 25,6: 36,7: 49,8: 64,9: 81}
A6 = [[0,0],[1,1],[2,4],[3,9],[4,16],[5,25],[6,36],[7,49],[8,64],[9,81]]
