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
