Iterate over rows in Pandas dataframe Using iterrows: for index, row in df.iterrows(): print (row["name"], row["age"]) Willard Morris 20 Al Jennings 19 Omar Mullins 22 Spencer McDaniel 21 Using itertuples: for row in df.itertuples(index=True, name='Pandas'):...
This method applies a function to each row or column of the DataFrame. The function can be passed as an argument and is applied to each row, and the results are combined into a new DataFrame. Here is an example of how to use theapply()method to iterate over rows: ...
