Level Up Your Strings

4:12 with Megan Amendola

Take your strings and inputs to the next level with string formatting.

Let's take a look at the code we've written so far. 0:00
Looking great, but there's one thing that's bothering me. 0:03
We're printing out these pieces of a sentence using multiple print statements, 0:06
making them look a bit messy in the console instead of a nice single 0:11
line sentence. 0:15
Was it bothering you too? 0:18
Well, you're thinking, there's got to be a better way, Megan. 0:19
[LAUGH] Well, I'm here to tell you there is, it's called string formatting. 0:23
It allows us to pass in our variables into our strings. 0:29
It will help us reduce the amount of code we've written and be a bit neater. 0:34
Now, there are a few ways to do this, I'm only going to show you one way, and 0:38
if you decide to move forward with Python, you will learn the other methods. 0:43
In front of the My name is string, in between the opening parenthesis and 0:49
the first quotation mark, add the letter f. 0:56
This stands for format. 1:00
It tells Python that there will be some extra tasks to do with this string, 1:03
before it prints it to the console. 1:07
Then, at the end of the message, 1:11
we can add our name variable, and 1:14
it will be inside curly brackets, {name}. 1:18
This tells Python to find the variable name and add what it equals to 1:24
the string right here, then you can delete the print statement below. 1:29
And let's see this in action. 1:36
Save and let's run the file. 1:39
Enter in any name you want. 1:45
And voila, our name was placed inside of your message. 1:51
Now, can you do the same thing for the last name below? 1:57
Go ahead and pause me and try converting it on your own. 2:02
When you finished or if you get stuck, unpause me and see how I did it. 2:05
I'm going to add a space. 2:13
And then, curly bracket, last_name, 2:15
closing curly bracket, and remove last_name. 2:19
Save and run the file to check your work. 2:25
Sweet, it all works. 2:34
It's time to practice. 2:37
Create a new variable called color. 2:39
And ask the user what their favorite color is. 2:45
Then print out a message in the console, my favorite color is, and 2:48
add the variable into the string using string formatting. 2:52
Pause me and give it a go. 2:57
Okay, let's tackle this challenge. 3:02
Color = input ( 'What is 3:04
your favorite color?'), 3:09
and then down here, 3:15
below our print statement, 3:19
we'll do print ( f 'My favorite 3:24
color is {color}'). 3:31
Save and run the file. 3:36
Megan Amendola. 3:45
My name is Megan, my favorite color is green. 3:53
Challenge complete. 3:56
What other questions can you ask your user? 3:58
Practice creating variables, asking for input, and 4:01
printing formatted strings on your own. 4:04
The more you practice, the more the knowledge will stick. 4:08
