分享一篇pandas實現選取特定索引的行的方法，希望對你有所幫助：
>>> import numpy as np
>>> import pandas as pd
>>> index=np.array([2,4,6,8,10])
>>> data=np.array([3,5,7,9,11])
>>> data=pd.DataFrame({'num':data},index=index)
>>> print(data)
num
2 3
4 5
6 7
8 9
10 11
>>> select_index=index[index>5]
>>> print(select_index)
[ 6 8 10]
>>> data['num'].loc[select_index]
6 7
8 9
10 11
Name: num, dtype: int32
>>>
注意，不能用iloc，iloc是將序列當作數組來訪問，下標又會從0開始：
>>> data['num'].iloc[2:5]
6 7
8 9
10 11
Name: num, dtype: int32
>>> data['num'].iloc[[2,3,4]]
6 7
8 9
10 11
Name: num, dtype: int32
>>>
可以試試看
