Finally, it saves the DataFrame as a CSV file named ‘GFG.csv’ using the tocsv method. Use the Search Bar in the upper right corner. 1 Create Data 1.1 Create Lists 1.2 Create Tuples 1.3 Create Numpy Arrays 1.4 Create Strings 1.5 Create Dictionaries 1.6 Create Pandas Objects 1.7 Create SQL Databases 2 Export 2.1 Export Data Frames 2.2 Export Dictionaries 2.3 Export Lists 2.4 Export Strings 2.5 Export SQL Tables 3 Import 3. The lack of a well-defined standard means that subtle differences often exist in the data produced and.
