采用iterrows的方法,得到的 row 是一个Series,DataFrame的dtypes不会被保留。 返回的Series只是一个原始DataFrame的复制,不可以对原始DataFrame进行修改; itertuples http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.itertuples.html importpandasaspd inp = [{'c1':10,'c2':100}, {'c1'...

Pandas is a powerful library for working with data in Python, and the DataFrame is one of its most widely used data structures. One common task when working with DataFrames is to iterate over the rows and perform some action on each row. ...

Pandas DataFrame - itertuples() function: The itertuples() function is used to iterate over DataFrame rows as namedtuples.
First, you will call the .apply() method on the basebal_df dataframe. Then use the lambda function to iterate over the rows of the dataframe. For every row, we grab the RS and RA columns and pass them to the calc_run_diff function. Finally, you will specify the axis=1 to tell the...
