Python-如何在pandas DataFrame中对连续值进行分组

你可以groupby通过自定义使用

Series

df = pd.Dataframe({'a': [1, 1, -1, 1, -1, -1]})print (df)   a0  11  12 -13  14 -15 -1print ((df.a != df.a.shift()).cumsum())0    11    12    23    34    45    4Name: a, dtype: int32

for i, g in df.groupby([(df.a != df.a.shift()).cumsum()]):    print (i)    print (g)    print (g.a.tolist())   a0  11  1[1, 1]2   a2 -1[-1]3   a3  1[1]4   a4 -15 -1[-1, -1]
