【Pandas】【碎碎念】 数据list对象去重，转字符串

Others 2021-11-26 10:06:08 views: null
  1. list对象去重，利用set方法去重
rawIP['attack_mode_name_cn'].apply(set)
  1. 去重后转换回list对象
rawIP['attack_mode_name_cn'].apply(set).apply(list)
  1. 去重后转字符串对象
rawIP['attack_mode_name_cn'].apply(set).str.join(',')
  1. 去重时，考虑list对象顺序
rawIP['attack_mode_name_cn'].apply(lambda x: ','.join(dict.fromkeys(x).keys()))
