你可以用你的条件分配你的 value_counts
子集,然后得到那个 Series
的索引,然后用 isin
您可以检查应该在原始数据中的值,然后将值传递给原始数据帧:
You could assign you subset your value_counts
with your condition then get index of that Series
then with isin
you could check for the values which should be in your original and then pass values to the original DataFrame:
s = df['a'].value_counts()
df[df.isin(s.index[s >= 2]).values]
工作原理:
In [133]: s.index[s >= 2]
Out[133]: Int64Index([0, 2], dtype='int64')
In [134]: df.isin(s.index[s >= 2]).values
Out[134]:
array([[ True],
[False],
[ True],
[ True],
[ True],
[ True]], dtype=bool)
In [135]: df[df.isin(s.index[s >= 2]).values]
Out[135]:
a
0 0
2 0
3 0
4 2
5 2
