Python组织列表

对列表做一些操作。

#coding=utf-8

family=['father','mother','sister','grandfather','grandmother']
print(family)
print(family[1])
print(family[2].title())
print(family[-1])   #负数代表倒数

message="my best love is "+family[2].title()
print(message)
family[2]='yun'
print(family)
family.append('wife')   #在列表最后添加
print(family)
family.insert(3,'me')	#插入一个元素
print(family)
del family[3]	#删除元素
print(family)

old_family=family.pop()	#弹出最后一个元素
print(family)
print(old_family)
family.insert(1,'me')
print(family)
me=family.pop(1)	#弹出任意位置的
print(family)
family.append('wife')
print(family)
family.remove('wife')	#移除指定数据
print(family)

family.sort()	#按字母顺序排序（永久）
print(family)
family.sort(reverse=True)	#字母倒序排列（永久）
print(family)	
family.append('wife')
print(family)
print(sorted(family))	#暂时排序，原顺序不变
print(family)
family.reverse()	#倒序
print(family)
print(len(family))	#列表长度

for home in family:		#千万要记得打冒号
	print(home)				#简单循环
for home in family:
	print(home+" is my family")		#缩进里面的都是for语句

从代码中我们可以看到对列表的基本操作，排序啊之类的，最后是有一个简单的循环学习，后面有对循环的深入探讨。
