id และชื่อภาพภูเขาคืออะไรคะ?
What are the id and name of the photos for mountains?
df_photos = pd.DataFrame(columns=['mountain_id']); df_mountain = pd.DataFrame(columns=['id', 'name', 'height'])
df_mountain.merge(df_photos, left_on='id', right_on='mountain_id')[df_mountain['height'] > 4000][['id', 'name']]
