In this course, you will get a comprehensive overview of Python. You will start by laying the foundation and learning the introductory topics like operators, conditional statements, functions, loops, assignment statements, and more. You will then move onto more advanced topics such as classes and inheritance, iterators, list comprehensions, and dictionaries. Along with this, you will also get to explore the concept of testing and take a look at how GUI applications can be designed using Tkinter, Python's standard GUI library. 

By the time you're done, you'll be able to hit the ground running and be equipped with the tools that will allow you to be productive in Python.

Python 3: From Beginner to Advanced

## Problem statement

You have been provided with a `groceries` dictionary that contains the **names** of the customer as the **key** and the number of items they bought each day in a week as a list of **values**. 
```python
groceries = {
    "James": [10, 2, 5, 7, 9, 4, 6],
    "Tom": [1, 12, 3, 0, 1, 2, 5],
    "Sam": [9, 5, 4, 3, 2, 1, 3], 
}
```
Therefore, your task is to write the `most_purchases()` function. This function takes in the `groceries` dictionary and returns the **name of customer** who has made the **most purchases** in a week, along with their **total purchase**. 

## Input

```python
groceries = {
    "James": [10, 2, 5, 7, 9, 4, 6],
    "Tom": [1, 12, 3, 0, 1, 2, 5],
    "Sam": [9, 5, 4, 3, 2, 1, 3], 
}
```

## Output

```python
("James", 43)
```

## Challenge

This problem has been designed for you to practice freely with it, so try to solve it on your own first. Take some time and think about the different concepts we've explored in the course so far.

If you feel stuck, you can always check out the solution review provided in the next lesson.

Good luck!
