1.min(),max()
2.enumerate梅舉：依次返回索引值和對應的value值
3.zip：直接返回字典，按照自己的方式拼接

#最大、最小

In [1]: min(2,4)
Out[1]: 2

In [2]: max(2,4)
Out[2]: 4

#1-100之和

In [3]: sum(range(1,101))
Out[3]: 5050

#1-100偶數之和

In [4]: sum(range(2,101,2))
Out[4]: 2550

#1-100奇數之和

In [5]: sum(range(1,101,2))
Out[5]: 2500

#enumerate列舉：返回索引值和對應的value值

In [8]: for i,v in enumerate('hello'):
   ...:     print(str(i) + '--------->' + v)
   ...:
0--------->h
1--------->e
2--------->l
3--------->l
4--------->o

#zip以自己的方法一一對應

In [9]: s1 = 'abc'

In [10]: s2 = '123'

In [11]: for i in zip(s1,s2):
    ...:     print(i)
    ...:
('a', '1')
('b', '2')
('c', '3')
 

#以空對應

In [12]: for i in zip(s1,s2):
    ...:     print(''.join(i))
    ...:
a1
b2
c3

#以-對應

In [13]: for i in zip(s1,s2):
    ...:     print('-'.join(i))
    ...:
a-1
b-2
c-3
