Python - 'TypeError: '<=' not supported between instances of 'str' and 'int''

Question

I have a df column that has values ranging from -5 to 10. I want to change values <= -1 to negative, all 0 values to neutral, and all values >=

Answer 1

Another alternative is to define a custom function:

def transform_sentiment(x):
    if x < 0:
        return 'Negative'
    elif x == 0:
        return 'Neutral'
    else:
        return 'Positive'

df['Sentiment_new'] = df['Sentiment'].apply(lambda x: transform_sentiment(x))
