I have a column in my dataframe that is called delivery period. The delivery period is supposed to be in the format 'Month Year' (January 2025). It shows as the string "2025-01-01 to 2025-12-31". I need to identify where this occurs and create a new row for each month with the same data. For instance: Price Curve Text Delivery Period TEST TEST 2025-01-01 to 2025-12-31 some curve some text June 2025 some curve some text July 2025 some curve some text August 2025 some curve some text September 2025 some curve some text October 2025 some curve some text November 2025 some curve some text December 2025 to Price Curve Text Delivery Period TEST TEST January 2025 TEST TEST February 2025 TEST TEST March 2025 TEST TEST April 2025 TEST TEST May 2025 TEST TEST June 2025 TEST TEST July 2025 TEST TEST August 2025 TEST TEST September 2025 TEST TEST October 2025 TEST TEST November 2025 TEST TEST December 2025 some curve some text June 2025 some curve some text July 2025 some curve some text August 2025 some curve some text September 2025 some curve some text October 2025 some curve some text November 2025 some curve some text December 2025 MRE: data_dict_cols = { 'Price Curve': [ "TEST", "some curve", "some curve", "some curve", "some curve", "some curve", "some curve", "some curve" ], 'Text': [ "TEST", "some text", "some text", "some text", "some text", "some text", "some text", "some text" ], 'Delivery Period': [ "2025-01-01 to 2025-12-31", "June 2025", "July 2025", "August 2025", "September 2025", "October 2025", "November 2025", "December 2025" ] } df = pd.DataFrame(data_dict_cols) Continue reading...
