When execute following statement from .ipynb file `neg_idx = df[(df.news_category=='technology') & (df.sentiment_score == -15)].index[0]

I get following IndexError Traceback (most recent call last)

in ----> 5 neg_idx = df[(df.news_category=='technology') & (df.sentiment_score == -15)].index[1] ~/anaconda3/envs/myenv/lib/python3.7/site-packages/pandas/core/indexes/base.py in __getitem__(self, key) 2082 2083 if is_scalar(key): -> 2084 return getitem(key) 2085 2086 if isinstance(key, slice): IndexError: index 1 is out of bounds for axis 0 with size 0` Any assistance will be appreciated.
