python - Pandas Dataframe - 隔离值

Question

我有一个数据框(见下文)，我想运行它来隔离高于特定数字(60)的值并让它返回月份，我该怎么做:

   Month   Increase

0   Jan     34
1   Feb      4   
2   Mar     33
3   Apr     12
4   May     66

Answer 1

IIUC您可以使用boolean indexing :

mask = df.Increase  > 60
print (mask)
0    False
1    False
2    False
3    False
4     True
Name: Increase, dtype: bool

print (df[mask])
  Month  Increase
4   May        66

print (df.loc[mask, 'Month'])
4    May
Name: Month, dtype: object
