Problem 1: Round-trip to a CSV Dump the dataframe to a CSV and then read it back. Even though duplicate columns are supposed to be legal, Pandas won't allow that in the CSV import/export. df = pandas.DataFrame([[1,2]], columns=['a','a']) #Note df has two identically named ...
Step 7: Using .to_json() Function The inherent methods of Pandas Series and DataFrame objects allow streamlined exporting of different file formats including to_html(), to_json(), and to_csv(). json_export = docs.to_json() # return JSON data print ("nJSON data:", json_export) These...
