1.remove(删除指定值的元素)
x = ['to','be','or','not','to','be']
x.remove('be')
x
['to','or','not','to','be']
2.reverse(按照相反的顺序排列列表中的元素)
s = [1,2,3]
s.reverse()
s
[3,2,1]
3.sort(按顺序排列)
x = [2,3,4,5,7,9,6,0]
x.sort()
x
[0,2,3,4,5,6,7,9]
sorted函数
x = [4,6,2,1,7,9]
y = sorted(x)
x
[4,6,2,1,7,9]
y
[1,2,4,6,7,9]
4.高级排序：方法sort接受两个可选参数:key和reverse
x = ['aardfgasgas','sasasasas','a','aaa']
x.sort(key = len)按照长度来排序
x
['a','aaa','sasasasas','aardfgasgas']
x = [4,6,5,7,2,1]
x.sort(reverse=True)指定一个值true or false,是否按照相反的顺序排序
x
[1,2,4,5,6,7]
