python 基本函数

zip()

zip  压缩文件 经常看到，python的zip()函数 也可以形容为压缩

 

压缩：
a = [1, 2, 3, 4]
b = [11, 22, 33, 44]
c = zip(a, b)
print(c)
for i in c:
    print( i)

输出：
<zip object at 0x0000011EE807FF48>
(1, 11)
(2, 22)
(3, 33)
(4, 44)

解压：
a = [1, 2, 3, 4]
b = [11, 22, 33, 44]
c = zip(a, b)
d = zip(* c)
for k in d:
    print(k)
输出：
(1, 2, 3, 4)
(11, 22, 33, 44)
