Python Pandas lambda for update column with
lambda x: np.nan if x == '0/0' else df['RatioFraction']



Filter on one column then use lambda to change conditional on np.nan for no vote (0/0).



Received



TypeError: object of type 'float' has no len()


Code:



df['RatioFraction'] = df_ff_reviews['VoteRatio'].apply(lambda x: np.nan if x == '0/0' else df['RatioFraction'])









share|improve this question
























  • How do I code the apply function, e.g., apply(str.len) inside this lambda function to remove the object type no len()?

You can try np.where:



df['RatioFraction'] = np.where(df['VoteRatio'] == '0/0', np.nan, df['VoteRation'])

    Try this:



    df['RatioFraction'] = df_ff_reviews['VoteRatio']

    df['RatioFraction'].loc[df['RatioFraction'] == '0/0'] = np.nan
