python 基础2 编码转换 pycharm 配置 运算符 基本数据类型int str list tupple dict for循环 enumerate序列方法 range和xrange

li=[11,22,33]
foriinli:
print(li.index(i),i)

li=[11,22,33]
fork,vinenumerate(li,1):
print(k,v)

printrange(1,10)
#结果：[1,2,3,4,5,6,7,8,9]

printrange(1,10,2)
#结果：[1,3,5,7,9]

printrange(30,0,-2)
#结果：[30,28,26,24,22,20,18,16,14,12,10,8,6,4,2]

例如：

print(range(1,10))
　　输出range(1,10)而不是123.。。10

range用法：stop不匹配

　range(start,stop,sep)

　　比如range(1,10,2)

　　　　打印13579

　　range（10,1,-1）

　　　　　　10987...2
