## ~ Solve Problems and Learn how to code in Python

### 8a - Use Lists, string manipulation, functions, iteration and more to complete this ONLINE SHOPPING (Create Basket and Checkout) Program

An online store stores a list of their products (with Item ID and Cost) in a list. They want a demo program that allows customers to browse products, add to basket, and then checkout and produce a total £ of what is in their basket. The checkout feature is not expressly mentioned in the task, but this is an essential skill that you would do well to learn at this stage!

### Challenge - use lists, string manipulation, functions, iteration and more to solve this challenge.

First, watch the demo video below. Your task is to code something like this, and use the code below to get started

You can either edit and code online in repl.it or you can simply cut and paste the below into your own python file

```#Task - first test the program by inputting "001"
#Add 5 more products with details to the list
#Create a main menu that allows a customer to 1. Browse Products 2. View Basket
#Note: Add the products selected (for viewing) by the user to another list called "basket"

#this is a list that contains product informaton
product = ["001", "iphone", "£900", "002", "samsung", "£1020", "003", "toshiba", "£700"]

#stores whether the product has been found
found= False

#asks the user to enter a product code
product_code=input("Enter the product code of the item: ")

#a loop that will repeat for the length of the list
for x in range(0,len(product)):
#checks if the product code entered matches the current element of the list being checked
if product[x] == product_code:
#if it is it prints the name and cost
print(product[x + 1])
print(product[x + 2])
#sets found to true as the product is found
found = True
if found==False:
```

Systems Life Cycle (in a nutshell): Analyse - Design - Create - Test - Evaluate. Designing something or writing out some pseudocode before you actually write code is always a good idea! Get in to the habit of doing so! You can draw your flowchart here and screenshot it.

A sample flow chart (design) for this particular challenge could look like:

Each challenge section below provides an online drawing tool where you can dynamically create flowcharts. Screenshot them into your presentation for submission.
