Oct 20, 2021 · To actually iterate over Pandas dataframes rows, we can use the Pandas .iterrows () method. The method generates a tuple-based generator object. This means that each tuple contains an index (from the dataframe) and the row’s values. One important this to note here, is that .iterrows () does not maintain data types.

The df.iteritems() iterates over columns and not rows. Thus, to make it iterate over rows, you have to transpose (the "T"), which means you change rows and columns into each other (reflect over diagonal). As a result, you effectively iterate the original dataframe over its rows when you use df.T.iteritems() –
03.01.2019 · Iteration is a general term for taking each item of something, one after another. Pandas DataFrame consists of rows and columns so, in order to iterate over dataframe, we have to iterate a dataframe like a dictionary. In a dictionary, we iterate over the keys of the object in the same way we have to iterate in dataframe.
