pandas全表查询定位某个值所在行列的方法

时间:2022-11-07 19:07:36

如下所示:

?
1
2
3
# create a dataframe with an integer feature and a categorical string feature
demo_df = pd.DataFrame({'Integer Feature': [0, 1, 2, 1], 'Categorical Feature': ['socks', 'fox', 'socks', 'box']})
demo_df

接下来用for遍历:

?
1
2
3
4
5
for indexs in demo_df.index:
  for i in range(len(demo_df.loc[indexs].values)):
    if(demo_df.loc[indexs].values[i] =='fox'):
      print(indexs,i)
      print(demo_df.loc[indexs].values[i])

或者用列表推导式:

?
1
2
Categorical FeatureInteger Feature0socks01fox12socks23box1
[ (indexs,i) for indexs in demo_df.index for i in range(len(demo_df.loc[indexs].values)) if(demo_df.loc[indexs].values[i] =='fox')]
