python list里去重复的元素

1.通过set 函数进行实现，非常简单。

• #!/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
