What does Iteritems do in pandas? iteritems() function iterates over the given series object. the function iterates over the tuples containing the index labels and corresponding value in the series. How much faster is Itertuples? Itertuples() Solution This solution only took 8.68 seconds to execute which is about 83x faster compared to the iterrows() solution. How can I make pandas loop faster? Itertuples convert the data frame to a list of tuples, then iterates through it, which makes it comparatively faster. Vectorization is always the first and best choice. You can convert the data frame to NumPy array or into...
