如何使用python考虑其他两个变量对一个变量应用过滤器

Question

I am having data with variables participants , origin , and score . And I want those participants and origin whose score is greater than 60 . That means to filter participants I have to consider origin and score. I can filter only on origin or only on score but it will not work.

If anyone can help me, its great!!!

I think you can use boolean indexing :

df = pd.DataFrame({'participants':['a','s','d'],
                   'origin':['f','g','t'],
                   'score':[7,80,9]})

print (df)
  origin participants  score
0      f            a      7
1      g            s     80
2      t            d      9

df = df[df.score > 60]
print (df)
  origin participants  score
1      g            s     80
