>>> list(zip([1,3,5,7],[2,4,6,8]))
[(1, 2), (3, 4), (5, 6), (7, 8)]
把两个列表合成一个
也可以用map函数:
>>> list(map(lambda x,y:[x,y],[1,3,5,7],[2,4,6,8]))
[[1, 2], [3, 4], [5, 6], [7, 8]]
map函数:
map(F, multi-para)
F是个函数,后面可以带多个参数
>>> def format_name(s):
s1=s[0:1].upper()+s[1:].lower()
return s1
>>> list(map(format_name,['adam','help']))
['Adam', 'Help']
