Ctrl + Enter will execute a cell (or the play button in the upper left corner)

Are you getting any errors?

NameError Traceback (most recent call last)
in <cell line: 1>()
----> 1 sales[‘Customer_Age’].mean()

NameError: name ‘sales’ is not defined

4

name ‘sales’ is not defined

Do you have a variable called sales with some data in it?

Can you post your code here please?

5

sales = pd.read_csv(
‘data/sales_data.csv’,
parse_dates=[‘Date’])

This error suggests that the ‘sales’ DataFrame has not been defined in the current scope.

import pandas as pd

sales = pd.read_csv('data/sales_data.csv', parse_dates=['Date'])
sales['Customer_Age'].mean()
