python list里去重复的元素
1.通过set 函数进行实现，非常简单。点击(此处)折叠或打开
[*]#!/usr/bin/python
[*]list_string = ['123','abc','abc','cde']
[*]list_string = list(set(list_string))
[*]print list_string
输出的list就是去掉重复的结果
2.
[*]#!/usr/bin/python
[*]# Filename: DeleteRep
[*]# use: to delete the repetation of the string
[*]
[*]StringList=['123','abc','abc','cde','cde']
[*]index = 1
[*]compare = 0
[*]length = len(StringList) - 1
[*]while index <= length:
[*] if cmp(StringList[index],StringList[compare]) == 0:
[*] del StringList[index]
[*] length -= 1 #每次del之后List长度都减少
[*] if index == length + 1: #限制最后出现末尾两个是重复的现象的终止
[*] break
[*] else:
[*] index += 1
[*] compare += 1
[*] print StringList
