>>> list1=[1,45,232,45,666,64]>>> list2=["ss","kein","tom","sda","qq","da"]>>> d=dict(zip(list1,list2))>>> print(d){1: 'ss', 45: 'sda', 232: 'tom', 666: 'qq', 64: 'da'}

zip，实现把两个list组合成一个dict

格式为： dict(zip(keys,vals))

>>> L1=[1,2,3,4]>>> L2=[5,6,7,8]>>> zipped=zip(L1,L2)>>> print(zipped)
     
      >>> print(list(zipped))[(1, 5), (2, 6), (3, 7), (4, 8)]>>> print(dict(zipped)){}>>> print(dict(zip(L1,L2))){1: 5, 2: 6, 3: 7, 4: 8}>>> print(list(zip(L1,L2)))[(1, 5), (2, 6), (3, 7), (4, 8)]
     

 

 再举例map的用法：

>>> l=[1,3,5,7,9,10]>>> def add100(x):	return x+100>>> map(add100,l)
