Managing missing data is one of pandas' core strengths. Users can fill, interpolate, or drop NaN values directly within a DataFrame to create clean and complete datasets for analysis or integration into machine learning pipelines. Python and pandas ...
df.interpolate(method=’linear’) df.fillna(value=0) 34. How can we use pivot and melt data in Pandas? In Pandas, “pivot” and “melt” functions are essential tools for reshaping data. a. Pivot: It restructures data, typically from long to wide format, based on column values. For...

Series.interpolate([method, axis, limit, ...]) Interpolate values according to different methods. Reshaping, sorting Series.argsort([axis, kind, order]) Overrides ndarray.argsort. Series.reorder_levels(order) Rearrange index levels using input order. Series.sort_values([axis, ascending, ...]) ...
But .resample() also offers additional methods not available with .asfreq(). For example, we could use the .interpolate() method, which estimates values at new time points by finding points along a straight line between existing data points. df.mean_temp.resample('H').interpolate() Powered ...
