'Displaying data from a column of my dataframe in a web page
I want to display the rows of a column of my dataframe in a web page. I get an error on the following line:
return render(requete, 'analyse/index.html', context={'data': df['EXTERNAL_DATA2'].tolist()})
Below is the error that is displayed:
TypeError: list indices must be integers or slices, not str

Probably (based on the error message) df is not a pandas.DataFrame object but a list. Depending on its inner structure you might try (untested)
df2 = pandas.DataFrame(df)
return render(requete, 'analyse/index.html', context={'data': df2['EXTERNAL_DATA2'].tolist()})
In general you should debug data-related problems outside of your web application. Django and randering your data to html only adds unnecessary complexity here. I would recommend, to use jupyter or ipython to interactively explore your data only then process it in the webapp.
