pandas.DataFrame.iterrows — pandas 0.16.2 documentation (original) (raw)

DataFrame.iterrows()¶

Iterate over rows of DataFrame as (index, Series) pairs.

Returns:	it : generator A generator that iterates over the rows of the frame.

Notes

iterrows does not preserve dtypes across the rows (dtypes are preserved across columns for DataFrames). For example,

df = DataFrame([[1, 1.0]], columns=['x', 'y'])
row = next(df.iterrows())[1]
print(row['x'].dtype)
float64
print(df['x'].dtype)
int64
