Accessing specific data in an object created from a .csv file python

Question

I hope you can help me here, this is probably something simple but its driving me crazy trying to figure it out. So I have used pandas to read data from a csv file into an object "data". If I run "print(data)" I get the first section from the command line below. I want to access the name and the price. "print(data.at[i, "Name"])" works great for the Name column, where I is just a loop counter and represents the rows. However I can't access the price. I thought "print(data.at[i, "price"])" would have worked but it throws the error as you can see from the command line read out below. My full code follows the command line read out.

The above exception was the direct cause of the following exception:

My code

    import pandas as pd
    data = pd.read_csv("data.csv")

    print(data)

    i = 1
    while i < 6:
      print(data.at[i, "Name"])
      print(data.at[i, "price"])
      i += 1

Answer 1

A KeyError indicates no column called 'price' exists - maybe a space got in the way?

Try calling data.columns to see the exact names of your columns.

Answer 2

I believe the issue is with your column name. It looks like "Regular price" to me.
