字典dict

1.使用enumerate将list转换为dict

name=["lvjy","qilin","haidi"]
for item in enumerate(name):
    print(item)

name=["lvjy","qilin","haidi"]
for key,item in enumerate(name):
    print(key,item)

 2.input输入的内容为字符串，若要使用数字属性，需要进行转换

str=input("")

digit=int(str)

3.

python2.7:xrange

python3:range，for循环的时候才创建

4.dic.update({'name':'lvjy'})
