The other option for creating your DataFrames from python is to include the data in a list structure. The first approach is to use a row oriented approach using pandasfrom_records. This approach is similar to the dictionary approach but you need to explicitly call out the column labels. ...
Process: Manipulating data for analysis (grouping, filtering, aggregating, etc.) 3. Analyze: Conducting the actual analysis (if the user asks to plot a chart save it to an image in exports/charts/temp_chart.png and do not show the chart.) 4. Output: return a dictionary of: - type (...
