python中常用的内置方法

1.求最小值

In [1]: min(3,4)                                                                
Out[1]: 3

2.求最大值

In [2]: max(5,0)                                                                
Out[2]: 5

3.sum

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

In [4]: sum(range(1,101,2))                                                     
Out[4]: 2500

4.枚举

for i,v in enumerate('hello'):
     print(i,v)
运行结果：
1 e
2 l
3 l
4 o

5.zip

s1 = 'abc'
s2 = '123'
for i in zip(s1,s2):
    print(i)
    print(''.join(i))
运行结果：
('a', '1')
a1
('b', '2')
b2
('c', '3')
