# 去重 .duplicated s = pd.Series([1,1,1,1,2,2,2,3,4,5,5,5,5]) print(s.duplicated()) print(s[s.duplicated() == False]) print('-----') # 判断是否重复 # 通过布尔判断,得到不重复的值 s_re = s.drop_duplicates() print(s_re) print('-----') # drop.duplicates移除重复 # inplace参数:是否替换原值,默认False df = pd.DataFrame({'key1':['a','a',3,4,5], 'key2':['a','a','b','b','c']}) print(df.duplicated()) print(df['key2'].duplicated()) # Dataframe中使用duplicated
