Write a DataFrame to the binary parquet format. Convert DataFrame from DatetimeIndex to PeriodIndex. Count non-NA cells for each column or row. It also allows a range of orientations for the key-value pairs in the returned dictionary. Sometimes we may have a need of capitalizing the first letters of one column in the dataframe which can be achieved by the following methods. It may not seem like much, but I've found it invaluable when working with responses from RESTful APIs. >pd.DataFrame(data_tuples, columns=['Month','Day']) Month Day 0 Jan 31 1 Apr 30 2 Mar 31 3 June 30 3.
