Extract rows between two specific cells pandas

Question

I need to extract n rows between the cells epic and story from the column col2.

This is my input:

import pandas as         


        

Answer 1

IIUC,boolean indexing with Series.mod to detect the change from epic to story after setting all values ​​to False before the first epic.

epic = df['col2'].eq('epic') 
story = df['col2'].eq('story')
df.loc[(epic | story).where(epic.cumsum().ge(1), False)
                     .cumsum()
                     .mod(2)
                     .eq(1)
                     .where(~epic, False)].reset_index(drop=True)

Output

      col1 col2   col3
0     az a   ac  hello
1  azs abv   ac   hola
