Removing index column in pandas when reading a csv

Question

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

del df['index'] 

after I set

energy = df.index 

which I found in another post but that results in "KeyError: 'index' "

Answer 1

When writing to and reading from a CSV file include the argument index=False and index_col=False, respectively. Follows an example:

To write:

 df.to_csv(filename, index=False) 

and to read from the csv

df.read_csv(filename, index_col=False)   

This should prevent the issue so you don't need to fix it later.
