Ready to move past Excel for complex business analysis? Then you’ll find this course very helpful.

This hands-on introductory Data Science course is aimed at professionals and students who don't have any experience with programming. It will help you advance your career by preparing you to conduct meaningful data analysis in Python on any dataset — large or small.

You’ll begin with the fundamentals of Python, with focus on CSV files in Python, covering concepts like data preprocessing and Exploratory Data Analysis (EDA). In the second half, you'll focus on predictive and inferential analysis using statistical and machine learning techniques, and learn how these techniques can help solve business problems.

Data Science for Non-Programmers

# 1. Top $5$ customers with the highest number of orders

import pandas as pd 
df = pd.read_csv('e_commerce.csv')

# solution 
temp = df.groupby('CustomerID').size()
temp = temp.sort_values(ascending=False)
temp = temp.iloc[:5]

print(temp)

We do this task in three steps:

* First, we group our data with `CustomerID` and call `size` to retrieve the number of times each `CustomerID` appeared in the data in **line 5**. 
* Second, we sort the values in descending order using `sort_values` in **line 6**.
* In the end, we just take the top 5 customers since they are already sorted.

This lesson provides solutions to the exercise on exploring E-Commerce Dataset in previous lesson.
