I have the following code which imports a CSV file. There are 3 columns and I want to set the first two of them to variables. When I set the second column to the variable “efficiency” the index column is also tacked on. How can I get rid of the index column?
df = pd.DataFrame.from_csv('Efficiency_Data.csv', header=0, parse_dates=False) energy = df.index efficiency = df.Efficiency print efficiency
I tried using
after I set
energy = df.index
which I found in another post but that results in “KeyError: ‘index’ “
DataFrames and Series always have an index. Although it displays alongside the column(s), it is not a column, which is why
del df['index'] did not work.
If you want to replace the index with simple sequential numbers, use
To get a sense for why the index is there and how it is used, see e.g. 10 minutes to Pandas.
