Python Projects for Beginners a ten-Week Bootcamp Approach to Python Programming

.split( )

I won’t go into too much detail with split simply because what it returns is a list and we haven’t covered those quite yet; however, I wanted you to see how to use this method. What it does is separate the words in the sentence into a group of words, stored within a list. Now don’t worry about lists just yet, we’ll get there. For now, let’s just see how this method works:

# converting a string into a list of words s = "These words are separated by spaces" print( s.split(" ") )

Go ahead and run the cell. The output results in a list of words “[‘These’, ‘words’,
‘are’, ‘separated’, ‘by’, ‘spaces’]”. We’ll come back to this method and why it’s important.

THURSDAY EXERCISES

1. Uppercasing: Try manipulating the string “uppercase” so it prints out as all uppercase letters. you’ll need to look up a new method.
2 . Strip Symbols: strip all the dollar signs from the left side of this string “$$John smith”. Try it with .lstrip( ) and .strip( ). To see a description on how to use the strip method further, try using the help function in python by typing the following:
>>> help(" ".strip)

Today you learned a handful of manipulation methods, but there are many more. Try experimenting with others that you find on the Web.
Friday: Creating a Receipt Printing Program
Welcome to your first project! We’ll be creating a very basic receipt printing program. For this week, as we’ve learned about variables, operators, and string manipulation, we’ll be using these skills in order to create this program.

To follow along, let’s continue from our “Week_02” notebook and simply add a markdown cell at the bottom that says, “Friday Project: Printing Receipts.”

Final Design

It’s always good to picture the design of what you’re trying to build. For larger projects, you’ll want to create a flow chart or some sort of design document that will keep you on track. This way you don’t sway from the intended result. For us, we’ll be building a small receipt printing program with the concepts we’ve learned, in which the output will look like Figure 2-2.

Let’s begin, shall we!
