python数组基础

1.定义数组

#dingyishuzumoney = []print len(money)  #changduwei0

2.往数组中插入元素

money = []money.append("张总")money.append("王总")money.append("李总")money.append("刘经理")money.append("保洁大妈")money.append("程序员的我")print len(money)    #6

注意如果执行报SyntaxError: Non-ASCII character '\xe5' in file...，那么需要在文件头部写上

#coding:utf-8

3.打印数组里的某个元素

#打印出素组中某个元素print money[4]  #保洁大妈

4.遍历数组（注意for后面的冒号）

money = ["张总","王总","李总","刘经理","保洁大妈","程序员的我"]for m in money:    print m

5.数组索引范围

money = ["张总","王总","李总","刘经理","保洁大妈","程序员的我"]for index in range(1,len(money)):    print money[index]"""王总李总刘经理保洁大妈程序员的我"""

range(1,len(money) 索引范围

6.删除某个元素

money = ["张总","王总","李总","刘经理","保洁大妈","程序员的我"]del money[3]print len(money)    #此时数组里只有5个元素了

7.删除某一个索引范围内的数组元素

money = ["张总","王总","李总","刘经理","保洁大妈","程序员的我"]del money[3:5]  #删除索引3-5,不包含5print len(money)    #4#删除了数组理的 "刘经理","保洁大妈"
