统计每行>3的数值出现次数

1. sample = {
   
2.     'a': np.random.randn(10).round(2),
   
3.     'b': np.random.randint(1,10,10),
   
4.     'c': np.random.randint(-2,10,10),
   
5. }
   
6. df = pd.DataFrame(sample)
   
7. df
   
8. #%%
   
9. df['count'] = df.apply(lambda x: len([s for s in x if s> 0]), axis = 1)
   
10. df
